Creamy Roasted Red Pepper Pesto Recipe
One thing you may not know about me is that pesto is one of my all-time favorite sauces for adding bold flavor to any meal. While running my meal prep business, quickly learned that a great sauce can elevate even the simplest meals to something extraordinary. I only wish I had this red pepper pesto recipe back then, I know it would have been a hit!
The inspiration for this recipe came while strolling through the pasta aisle at a specialty food store, where I spotted a jar of red pepper pesto. I knew right away I had to recreate it in a way that fit my dairy free lifestyle. The result? A rich, savory pesto with the classic basil and garlic base but an irresistible sweetness from roasted red peppers that takes it to a whole new level.
If you love roasted red peppers, you have to try my Roasted Red Pepper Pasta Sauce, it’s thick, creamy, and completely dairy free. I also have a Sundried Tomato Pesto Pasta that I make at least 2-3 times every summer when my garden is overflowing with fresh basil.
One of the reasons I love this pesto is because not only is it ready in 5 minutes, it’s incredibly versatile. Toss it with pasta, spread it on sandwiches, or use it as a flavorful topping for grilled chicken or fish. It also makes a delicious dip for veggies or a drizzle for grain bowls.
Ingredient spotlight
- Roasted red peppers – roasted red peppers add a sweet, smoky flavor to the pesto. I tend to use the jarred roasted red peppers (in water not oil). But you can also roast your own sweet bell peppers to use in this sauce.
- Fresh basil – nothing really compares to the flavor of fresh basil, especially in pesto. Be sure to remove any of the thick stems before adding it to the food processor or blender.
- Cashews – helps to thicken the sauce, I like using raw cashews because I always have them on hand and find they are less expensive than pine nuts. Use whatever nuts or seeds you have on hand for this.
- Garlic – adds a spicy bite that offsets the sweetness from the peppers well. I recommend grating or finely chopping the garlic to ensure you don’t get a big chunk of garlic in one bite.
- Olive oil – helps to emulsify the sauce, helping it thicken and stick together. Use an olive oil you enjoy the flavor of.
- Lemon juice – adds some brightness to the sauce.
How to make red pepper pesto
Drain the roasted red peppers (I like to also rinse them as well). Make sure there is no liquid hiding inside the pepper. Let them drain for a minute or two in a colander. Add fresh basil, minced garlic, olive oil, lemon juice, salt and garlic powder to a food processor and blend on high to break down the basil Add the cashews to the food processor and blend well to break them down as much as possible (about 1 minute). Be sure the cashews are fully broken down before adding the roasted red peppers. Add the roasted red peppers and blend well until the pesto has your preferred texture (you can leave it a little chunky or blend until completely smooth). Serve immediately or store in the fridge for a day for flavors to intensify.
Sam’s Success Tips
- Flavor gets better with time: This roasted red pepper pesto tastes even better the next day once the flavors have had time to blend together.
- Perfect for meal prep: Make a double batch and freeze half so you always have an easy sauce ready for pasta, sandwiches, grain bowls, or protein.
- For a thicker pesto: Add extra cashews for a richer, creamier texture.
- No jarred peppers? Roast your own: You can roast fresh red peppers in the oven, air fryer, or directly over a gas burner for an even deeper flavor. My go-to is air fryer roasted red peppers.

Recipe Notes
- Drain the roasted red peppers well to avoid watery pesto: Let the roasted red peppers sit in a colander for a few minutes before blending. Too much liquid can make the pesto thin and watery.
- Rinse jarred roasted peppers: The liquid in the jar can be acidic, so a quick rinse helps keep the flavor balanced.
- Use fresh basil: Fresh basil is essential for the classic pesto flavor and texture. Dried basil won’t work in this recipe.
- Use the right equipment: A food processor or high-speed blender works best for a smooth, creamy pesto.
- Fridge: Store any leftovers in the fridge for up to a week in a well sealed container.
- Freezer: Freeze leftovers in a freezer safe bag or container for up to 3 months. I like to freeze in Soupercubes then transfer the frozen block to a stasher bag for long term storage. Be sure to label the bag with the name, date and use by date.
- Defrost in the fridge before using the pesto. Give it a good stir before serving.

Common questions
Can you use dried basil in pesto
No. Fresh basil has a much brighter flavor than dried, so they cannot be substituted. If you don’t have fresh basil, you can simply omit it or replace it with fresh flat-leaf parsley for a slightly different but still delicious flavor.
How to make this nut free
Swap the cashews for sunflower seeds or pumpkin seeds. I recommend toasting them first for the best flavor.
Is red pepper pesto spicy?
This red pepper pesto is made with roasted red peppers which are actually sweet, not spicy.
If you would like the pesto to have a spicy kick, add about ½ teaspoon of red pepper flakes.
Should I heat this up?
You can enjoy this bell pepper pesto cold, warm or hot. The basil will lose some of it’s pungent flavor if heated but the pesto will still be delicious.
