Ingredients to make roasted red pepper pasta

  • Roasted Red Peppers: I like to use jarred roasted red peppers because they are already cooked, and it cuts down on the prep time. However, you can absolutely roast your own peppers if you prefer.
  • Onion: I used a white onion, but you can use any type of onion that you have on hand.
  • Garlic: I used fresh garlic and roasted it, but you can also use jarred minced garlic or even garlic powder. If you don’t use fresh, just add the jarred or powdered garlic to the food processor.
  • Plant-Based Milk: I used almond milk, but any type of plant-based milk will work in this recipe.
  • Seasoning: Olive oil, salt, and a sprinkle of crushed red pepper really help bring the flavor out in this pasta sauce!
  • Spaghetti: I used spaghetti, but you can use any type of pasta that you have on hand.

Tips to make bell pepper pasta sauce

  1. If you prefer to roast the peppers, just place them under the broiler for 3-5 minutes until they get charred. You can roast them whole without removing the seeds. Then, transfer them to a glass container, and cover them with saran wrap for 15-20 minutes, so the steam continues to cook and soften them. This is a wonderful method for roasting your own bell peppers, which results in an amazingly sweet and smoky flavor!
  2. Don’t over-char your onions and garlic. You want them to be nicely browned, not burnt.
  3. Make sure to drain your jar of roasted red peppers. Otherwise, your sauce will be too watery.
  4. Cook your pasta until just al dente. You want the pasta to absorb some of the sauce and not be too soggy.

popular substitutions & additions

  1. If you want to make this meal gluten-free or low-carb, try using spiralized vegetables like zucchini or even spaghetti squash and toss them with the sauce. You’ll have all the flavor and comfort of this sauce with fewer carbohydrates and calories.
  2. If you’d like to modify the flavor of the sauce, you can consider adding some crushed red peppers for some heat, some Italian seasoning for a more savory flavor, or even some nuts like cashews to give it a more nutty and cheesy flavor. Think of the roasted red peppers, onions, and garlic as the base for the sauce. And feel free to add your unique twist to the sauce and to the final dish.
  3. Use nutritional yeast in place of cheese. If you are vegan or lactose-intolerant, you can use nutritional yeast to add a cheesy flavor to the sauce. Just sprinkle it on top of the pasta once it is plated.
  4. Add some protein. If you want to add some protein to this dish, consider tossing in some cooked chicken, shrimp, or even tofu. You could also serve it with a side of grilled chicken or fish.

what to serve with your red pepper pasta sauce

how to store & reheat red pepper pasta sauce

This pasta sauce can be stored in an airtight container in the refrigerator. When you are ready to eat it, just reheat it on the stove over low heat until it is warmed through. You may need to add a splash of water or milk to thin it out since it will thicken as it sits in the fridge.

how long will roasted red pepper pasta last in the fridge?

When stored on its own, this red pepper pasta sauce will last in the fridge for up to one week. But, if you store it with cooked pasta, it will only last for a few days. So, if you want to make this ahead of time, I would recommend storing the sauce and pasta separately and then just reheating them when you are ready to eat.

can I freeze red pepper pasta sauce?

Yes, this pasta sauce can be frozen. Just store it in an airtight container, and it will last for up to three months. When you are ready to eat it, just thaw it overnight in the refrigerator and then reheat it on the stove over low heat until it is warmed through.

Frequently Asked Questions

Can you use different color peppers in this pasta dish?

Personally, red peppers are my favorite color to use in this recipe, and they are usually the easiest ones to find in stores. You can absolutely use orange or yellow peppers if you wish – it doesn’t take long to roast them yourself!

What’s the best pasta to use for this recipe?

I like making this dish with long pasta such as linguine or spaghetti, but you can of course use whatever you have to hand. You can use whole wheat pasta, too, if you wish for a meal with added fiber and whole grains.

My sauce came out too thick. What can I do?

If your sauce is too thick, simply add a little water or milk to thin it out. If you saved the water, your roasted peppers came in. You can try adding splash in to see if that does the trick.
