Pesto, the vibrant green sauce traditionally made from basil, garlic, pine nuts, Parmesan cheese, and olive oil, is a beloved staple in kitchens around the world. While store-bought pesto offers convenience, many home cooks find that it often lacks the depth of flavor and freshness of its homemade counterpart. The good news? You don’t have to settle for average. With a few simple techniques and ingredient upgrades, store-bought pesto can be transformed into a gourmet sauce that rivals any artisanal blend.
In this article, we’ll walk you through everything you need to know about upgrading store-bought pesto, including why it matters, how to enhance texture and taste, and creative ways to use your upgraded sauce. Whether you’re preparing a quick weeknight dinner or entertaining guests, these tips will ensure your pesto shines.
Why Upgrade Store-Bought Pesto?
Before diving into the how, it’s important to understand the why. Store-bought pesto is undeniably convenient, but it often comes with trade-offs, such as:
- Pasteurization processes that dull the freshness and brightness of herbs
- Added preservatives and stabilizers to prolong shelf life
- Lower-quality ingredients like sunflower oil instead of olive oil or dehydrated garlic instead of fresh
- Pre-ground nuts that can become rancid or lose their crunch
- Excessive sodium that can mask the delicate flavor of the herbs
Upgrading your pesto not only restores the fresh, aromatic quality that makes this sauce special but also allows you to tailor it to your personal tastes and dietary preferences.
How to Revitalize Store-Bought Pesto: Basic Upgrades
You don’t need a chef’s knife or a food processor to make a difference—just a few ingredients and techniques can elevate pesto from store-grade to impressive.
1. Add Fresh Basil
Store-bought pesto is often made with dried or less-than-fresh basil. Adding fresh basil leaves, or even basil flowers, can reintroduce a punch of herbaceous flavor.
- Chiffonade a handful of fresh basil and fold it into the pesto
- Alternatively, blend a few fresh basil leaves into your pesto for a more integrated taste
This technique also helps maintain a brighter green color.
2. Boost with Fresh Garlic
Most factory-made pestos use garlic that’s been dehydrated or pre-cooked. For a livelier taste:
- Mince 1–2 cloves of fresh garlic and mix them in
- For garlic lovers, consider roasting a few cloves and stirring in the softened cloves for a sweeter, more complex taste
3. Enrich with High-Quality Olive Oil
Many commercial pestos use lower-grade or blended oils to cut costs. To enhance richness and aroma:
- Add a spoonful of extra virgin olive oil
- Drizzle warm olive oil over the pesto and stir to combine
The result is a silkier texture and more pronounced peppery finish.
Enhancing Flavor and Texture: Advanced Upgrade Techniques
Once you’ve mastered the foundational upgrades, it’s time to take your pesto to the next level with more adventurous techniques and ingredients.
1. Toast the Nuts
Freshening up the nut component of pesto can dramatically improve its flavor. Walnuts, pine nuts, or almonds in store-bought versions are often stale or raw.
- Lightly toast 1/4 cup of your preferred nut in a dry skillet until fragrant
- Chop coarsely and fold into the pesto, or pulse in a food processor for a chunkier texture
The result is a nutty, buttery depth that store-bought versions tend to lack.
2. Stir in Freshly Grated Parmesan or Pecorino
Many commercial pestos use pre-grated, dried cheese that lacks the creamy, saline richness of freshly grated Parmigiano-Reggiano or Pecorino Romano.
- Grate a spoonful of quality cheese into your pesto
- Stir well until fully incorporated
This tweak enhances umami and texture simultaneously.
3. Emulsify with Avocado or Mascarpone
For a richer, creamier pesto that still maintains a vibrant flavor:
- Add 1/4 of a ripe avocado and blend until smooth
- Alternatively, mix in a spoonful of mascarpone or crème fraîche
This technique is particularly useful when serving pesto over pasta or using it as a dip or spread for sandwiches.
4. Add Citrus Zest
A touch of citrus brightens up the earthy, oily components in pesto.
- Grate a bit of lemon or lime zest and stir it in
- A few drops of lemon juice will also help balance the flavor
This step is especially effective when pairing pesto with seafood or serving it cold.
Using Herbs and Greens Creatively in Pesto
Basil is traditional, but pesto is essentially a blank canvas. You can use other greens to customize the flavor and nutritional profile.
Use Spinach for Creaminess
Spinach blends well into pesto and gives it a milder, sweeter flavor.
- Mix a handful of blanched or steamed spinach into the existing pesto
- Alternatively, partially replace the basil in your pesto base with spinach during processing
This variation is ideal for those who want a less intense, slightly earthy version.
Try Kale for Bitterness and Fiber
Kale can add a slightly bitter edge and a boost of fiber and iron.
- Add chopped, blanched kale and blend until smooth
- To reduce bitterness, massage the kale with olive oil before adding
Kale-based pesto is particularly robust and hearty, making it a perfect accompaniment for roasted vegetables or grilled meats.
Experiment with Other Herbs
Expand beyond basil by adding or substituting other herbs:
Mint: great with lamb
Cilantro: perfect for Latin or Indian-inspired dishes
Arugula: adds peppery notes
Rue or Lemon Verbena: infuse citrus tones
Mix and match to create exciting global flavor combinations.
Customizing Pesto for Dietary Needs and Preferences
Whether you’re feeding a vegan audience, avoiding dairy, or managing nut allergies, you can customize store-bought pesto to suit different dietary needs.
Making Pesto Vegan
Traditional pesto contains cheese, which can easily be substituted to make it vegan-friendly.
- Replace Parmesan with nutritional yeast for a savory, cheesy flavor
- Use cashews or hemp seeds instead of Parmesan for a protein-rich alternative
Stir in a bit of lemon juice for added tanginess and freshness.
Creating Nut-Free Pesto
For those avoiding nuts due to allergies:
- Replace walnuts or pine nuts with sunflower seeds or pumpkin seeds
- Use a seed-based cheese alternative or skip the cheese altogether
Seed-based pesto can be just as rich and creamy, depending on the oil used and emulsifying method.
Reducing Sodium in Pesto
Some store-bought pestos are packed with salt. To control the flavor:
- Rinse the pesto lightly with warm water (for jarred versions) and drain
- Blend in fresh herbs, cheeses, or other ingredients to dilute the saltiness
Alternatively, gradually mix in plain Greek yogurt or cottage cheese to mellow out the intense salty notes without losing texture.
Creative Ways to Use Upgraded Pesto in Your Cooking
Once you’ve boosted the flavor and texture of your pesto, the culinary possibilities expand beyond simple pasta tosses.
1. As a Sandwich Spread or Burger Base
Replace mayonnaise or mustard with pesto in sandwiches, wraps, and burgers. For a gourmet twist:
- Spread on toasted sourdough with grilled vegetables and goat cheese
- Use as a topping for turkey or chicken burgers
The result is a bold, flavorful, and colorful enhancement to your favorite handheld meals.
2. Stir Into Soups and Stews
A swirl of pesto into soups like tomato, potato, or even black bean adds a layer of richness and a pop of color.
- Add a spoonful to hot chicken noodle or lentil soup just before serving
- Drop into minestrone for a herby kick
Pesto can also be stirred into cool soups like gazpacho for a Mediterranean twist.
3. Elevate Eggs and Breakfast Dishes
From scrambled eggs to omelets, pesto can transform a simple breakfast into a lavish meal.
- Stir into scrambled eggs just before cooking
- Spread on avocado toast or English muffins for poached eggs
Pesto-infused breakfasts offer an unexpected gourmet flair.
4. Use as a Pizza or Flatbread Sauce
Swap traditional tomato sauce for pesto to create a lush green base.
- Use homemade or upgraded store-bought pesto on focaccia, flatbreads, or white pizzas
- Top with mozzarella, cherry tomatoes, or grilled shrimp
This variation is visually stunning and flavor-packed.
Storage and Shelf-Life Tips for Upgraded Pesto
After upgrading your pesto, proper storage ensures you can enjoy it across meals without compromising flavor or safety.
Refrigeration Basics
Homemade-style upgraded pesto will typically last for 5–7 days in the refrigerator if handled properly.
- Transfer pesto into an airtight glass jar
- Drizzle a thin layer of olive oil on top to prevent oxidization
- Store in the coldest part of the fridge
This slows oxidation and retains the vibrant green hue.
Freezing Pesto for Long-Term Use
To keep your upgraded pesto beyond a week:
- Pour pesto into ice cube trays and freeze individually
- Once frozen, transfer cubes to a resealable freezer bag and label with date
- Freeze pesto flat in small vacuum-sealed bags
Frozen pesto cubes are perfect for single-use additions to pasta, soups, and stews and can be stored for up to 6 months.

What are the best ways to enhance the flavor of store-bought pesto?
To elevate the flavor of store-bought pesto, start by adding freshly grated Parmesan cheese or Pecorino Romano. These cheeses provide a saltier, more complex umami punch than the pre-grated versions found in many commercial pesto sauces. Additionally, a drizzle of high-quality extra virgin olive oil can deepen the richness and complement the herbal notes of the basil.
Another effective method is to gently toast fresh garlic in olive oil before mixing it into the pesto, which brings out its natural sweetness while reducing its pungency. A squeeze of lemon juice also brightens the overall flavor profile, cutting through the oiliness and adding a refreshing contrast. Even a pinch of crushed red pepper flakes can provide a subtle layer of heat, enhancing the depth of flavor without overpowering the delicate balance of ingredients.
Can I add vegetables to store-bought pesto to improve it?
Yes, adding blanched or roasted vegetables is an excellent way to improve store-bought pesto both in flavor and nutrition. Vegetables like spinach, zucchini, or roasted red peppers add bulk, unique textures, and nutrients without detracting from the traditional character of pesto. When blended into the sauce, they can also make it creamier and more versatile for different dishes.
Leafy greens such as spinach or kale are particularly effective, as they blend smoothly and introduce additional fiber and vitamins. Roasted vegetables, on the other hand, contribute a caramelized sweetness that enriches the sauce. These additions can also make the pesto stretch further, making it a more economical and nutrient-dense option.
How can proteins be incorporated into pesto for a more satisfying meal?
Incorporating proteins into pesto can transform it from a condiment into a complete meal. A simple way is to mix in grilled chicken, shrimp, or tofu for a boost in satiety and nutritional value. These proteins complement the fresh, herbaceous flavor of pesto and work particularly well when tossed with pasta or spread on sandwiches.
For a vegetarian twist, consider adding white beans or chickpeas. They provide a hearty texture and are naturally high in fiber and protein, making the pesto more fulfilling. When blended partially, they give a creamy base that not only enhances the consistency but also gives the sauce a more substantial feel without compromising flavor.
Is it possible to make store-bought pesto healthier without losing flavor?
Yes, you can improve the nutritional profile of store-bought pesto without sacrificing flavor by incorporating more fresh herbs or greens. Adding fresh basil, cilantro, or arugula boosts antioxidant levels and adds vibrant flavor. These greens can be lightly blended into the existing pesto to maintain its creamy texture.
Another healthy tweak is to reduce the amount of cheese by substituting part of it with nutritional yeast, which offers a similar nutty and salty flavor while being lower in saturated fat. You can also introduce a spoonful of Greek yogurt to create a creamier texture while increasing protein content. These substitutions allow for a more nutrient-dense pesto that still satisfies the palate.
What herbs and spices can I use to customize the flavor of pesto?
Pesto can be customized using a variety of herbs and spices to suit different tastes and culinary themes. Fresh herbs like parsley, mint, or arugula add new dimensions when blended into the existing basil base. Parsley offers a milder flavor, mint introduces a refreshing twist, and arugula gives a peppery kick that elevates the overall flavor.
Spices such as smoked paprika, truffle salt, or dried oregano can also be used to enhance the pesto without overpowering its natural freshness. For more earthiness, consider mixing in a pinch of cumin or sumac for a nuanced, aromatic touch. Sprinkling these on top of the pesto before serving can create a signature flavor that matches the dish you’re preparing.
How can I adjust the texture of store-bought pesto?
Store-bought pesto often has a dense or overly oily consistency, but adjusting the texture is simple. Adding a small amount of water or pasta cooking water while stirring creates a silkier, more fluid texture that coats pasta better. This technique emulsifies the sauce, enhancing its ability to cling to ingredients.
Alternatively, you can thicken the pesto by mixing in finely ground nuts or breadcrumbs, which also introduce a richer mouthfeel. Roasted pine nuts or walnuts are ideal for boosting texture as well as flavor. If a chunkier pesto is desired, fold in coarsely chopped fresh herbs or nuts for a more rustic and dynamic consistency.
Are there creative ways to use upgraded pesto beyond pasta dishes?
Absolutely, upgraded pesto can be used in a variety of creative ways beyond traditional pasta dishes. Try using it as a spread on sandwiches or wraps for a fresh, savory kick. It also works beautifully as a base for flatbreads or pizzas, adding a vibrant layer of flavor before adding other toppings like vegetables or proteins.
Pesto can also be stirred into soups, blended into mashed potatoes, or drizzled over roasted vegetables for a gourmet twist. As a marinade or glaze for grilled meats and fish, it imparts a rich, herbal flavor that enhances the dish. These versatile applications make pesto a valuable ingredient throughout your meal planning, not just as a pasta topper.
