This roasted red pepper pesto is sweet, garlicky, and the perfect addition to pasta, pizza, and your favorite crusty bread.
I like to think of this recipe as the holy grail of pestos. Yes, it has basil in it, but it also has something even better: roasted red peppers. Roasting brings out the best in red bell peppers, adding a smoky flavor and making the crisp flesh tender and sweet. Combine those flavors with pesto and you’ve got yourself a sauce that you’ll want to keep on hand at all times.
Like most pestos, roasted red pepper pesto is great for tossing with pasta (try this recipe!), but why limit yourself? If you’re entertaining, you can put together an epic spread of crudités and rosemary bread with red pepper pesto, pistachio pesto, and olive pesto for dipping. Use this pesto in place of pizza sauce or swap it for the mashed avocado on a piece of toast.
What You’ll Need
If you don’t count the salt, pepper, and oil (which you probably have on hand anyway!), you’ll only need 4 ingredients for this roasted red pepper pesto.
- Red bell peppers – While you can buy roasted red peppers in a jar, making your own is best for this recipe because the end result is much more flavorful.
- Garlic
- Pine nuts – Pine nuts are definitely a love-it-or-hate-it kind of ingredient. Walnuts or almonds could be used instead.
- Basil leaves – After you wash them, give them a spin in your salad spinner or pat them dry with a paper towel.
- Salt
- Pepper
- Olive oil
Can I Add Parmesan?
A traditional basil pesto is made with parmesan cheese. If you like, you can add some grated parm before you process the ingredients, but this pesto is definitely flavorful enough on its own without it!
How to Make Roasted Red Pepper Pesto
This recipe is so easy to make, you’ll never want to buy store-bought pesto again! Here’s what you’ll need to do.
Prepare. Preheat your oven to 400ºF. Cut the peppers into large pieces and place them on a baking sheet with the skin side down. Drizzle with olive oil and season with salt.
Roast the peppers. Place the baking sheet in the oven and roast the peppers for 20 to 25 minutes, or until the peppers are soft and the skin is starting to char.
Toast the pine nuts. While the peppers are roasting, lightly toast the pine nuts in a small skillet set over medium heat.
Make the pesto. Combine the roasted peppers, garlic, pine nuts, and basil in your food processor. Turn it on and drizzle olive oil through the feed tube; continue to process until the pesto reaches a smooth, thick consistency, then season to taste with salt and pepper.
Tips for Success
Here are a few tips and tricks to make sure this recipe turns out perfect.
- Watch the pine nuts. Nuts and seeds can burn super fast on the stovetop, so keep an eye on the pine nuts while you’re toasting them in the skillet. Stir them often, too, to make sure they toast evenly.
- Don’t be afraid to add a lot of oil. It’s the secret to getting a rich, creamy pesto.
- No food processor? You can make this roasted red pepper pesto in a blender instead.
How to Store
Store roasted red pepper pesto in an airtight jar in the fridge for up to two weeks.
Can This Recipe Be Frozen?
Yes, you can freeze roasted red pepper pesto, so you might want to double the recipe and keep some on hand for easy dinners. Freeze it in an airtight container or freezer bag for up to 3 months; let it thaw in the fridge or place the freezer bag in a bowl of hot water to thaw it quickly.
