This no-cook roasted red pepper sauce is easy, healthy, and full of flavour. Serve it over pasta, with chicken or fish, or on burgers. This vegan recipe is quick to prepare and so versatile.

We adore homemade sauces in our house. In the summer, our go-to sauce recipes are my basil pesto and Greek yogurt chipotle sauce, but we have also been enjoying roasted red peppers lately.
A few weeks ago, I decided to whip up a roasted red pepper sauce consisting of cherry tomatoes, roasted red peppers, toasted walnuts, olive oil, lemon juice, salt smoked paprika, and cayenne. This was the delicious result!
It’s a simple no-cook sauce for the end of summer, but it can be enjoyed at any time of the year since it uses jarred roasted red peppers. I love tossing it with chickpeas and enjoying it alongside white rice, halloumi, and a simple arugula salad for a delicious vegetarian meal. Of course, it would also be delicious with pasta (especially tortellini), grilled chicken, fish, or steak, and eggs. The possibilities are endless.

Ingredients
Here is a list of ingredients that you’ll need to make this sauce. Scroll to the recipe card for exact quantities.

- Roasted red peppers: You’ll need a 16 ounce jar of roasted red peppers.
- Cherry tomatoes: These are optional. The sauce will be thicker without them.
- Walnuts: Start with raw walnuts and toast them in the oven or on a skillet until lightly browned and fragrant.
- Garlic: Essential for adding flavour to the sauce.
- Extra-virgin olive oil: To blend it into a smooth, creamy sauce.
- Lemon juice: For a tangy flavour.
- Smoked paprika and cayenne: For boldness and spice.
- Sea salt and pepper: To enhance the flavour of the sauce.
Instructions
Place all of the ingredients in a food processor and blend until your desired texture is reached. I like a smooth sauce, but some like it thicker/chunkier.
Hint: After blending, taste the sauce to see if it needs more salt or lemon juice. If it is too tangy for your liking, add a teaspoon of maple syrup or honey to balance out the flavours.
Substitutions and Variations
- Walnuts – instead of walnuts, use almonds or hazelnuts.
- Nut-Free – use sunflower seeds instead of walnuts to make this recipe nut-free.
- Add some Parmesan: This sauce would be delicious with the addition of finely shredded Parmesan cheese. Add about ¼ cup if you’d like an extra layer of flavour.

FAQ
Unlike some roasted red pepper sauces, this version is designed to be enjoyed at room temperature. Because it contains lemon juice, it should not be heated to a high temperature because the flavours will change. However, you can toss it with warm pasta or serve it over warm meat or eggs.
