Pasta night gets yummier with this homemade roasted red pepper pasta sauce. It is filled with rustic flavors from roasted red bell peppers, onions, garlic, and fire-roasted tomatoes. Vegan and gluten-free sauce recipe that you can make in advance.
There is something really good about roasted vegetables. I can have a bowl of it every day without complaining. No doubt that this Vegan Pasta Primavera with roasted vegetables is a family favorite.
I am really excited about sharing this sauce recipe with you. Though it is homemade, it is effortless. It has simple ingredients and is not as tart as the store-bought pasta sauce. I have been making it for a while now with red peppers, garlic, and onion alone. This time I happen to add a can of fire-roasted tomatoes and fresh parsley to it and omg the taste just rocketed sky-high.
It is so good that I ate a couple of spoons right out of the processor. So robust, rustic, and flavorful. You may think roasting is time-consuming. But honestly, it requires just 5 minutes of your prep time. Once it is in the oven there is no need to be around. I just set on the timer and let the oven do its job.
Once it is done, I cool it and finally blitz it in a blender or food processor. A delicious sauce is ready to go on your pasta. But why only pasta, I recommend this roasted bell pepper sauce on your pizza, as a dip or even tossing your favorite grain like quinoa or rice. This sauce is fantastic on roasted potatoes too.
Ingredient for roasted red pepper pasta sauce
Red bell peppers – No swaps here. Imparts sweet taste to the pasta sauce.
Onions & Garlic are a must for a flavorful sauce
Fire Roasted Tomatoes – Gives a good rustic kick to the sauce. You may roast fresh tomatoes with the peppers. Totally works!
Fresh Parsley – Using fresh herbs amplifies the taste of the sauce. Basil is a good choice as well.
Red chili flakes – I love a little heat in my pasta. Skip it if you are not a fan.
Dried herbs, salt, and pepper – I call them flavor bombs. I use this combo in every pasta dish.

How to make this recipe in an Instant Pot?
On days when I am really pressed on time, I make pasta in my Instant Pot.
This is what you need to do –
- Add pasta to the Instant Pot
- Switch on the IP on saute mode.
- Add in the water to the pasta level only. Trust me!
- Add in a sprinkle of salt, pepper, and a splash of olive oil.

- After the IP beeps wait for a minute and then carefully do QUICK RELEASE towards venting.
- Place a dishcloth on the knob and then perform a quick release.
- Next when the pin drops carefully open the IP lid.
- You may see some water still in the pot. Don’t worry it will be soaked by the pasta in no time creating a nice thick sauce.

Important notes to consider while making pasta in an Instant Pot
- Use the desired shape of pasta. Spaghetti works well too.
- Always cook pasta for a minute less than half the time mentioned on the package.
- If says 10 minutes to al dente, then cook it for 10-5-1 = 4 minutes.
- I have not tried gluten-free pasta in an Instant Pot yet.
- Always place a kitchen towel or a dishcloth over the black knob before releasing it. This is done to avoid any liquid to splatter out of the Instant Pot.

What a great recipe! I topped my pasta with fresh ricotta and some garlic chips and it was *chef’s kiss*. Going to come back to this recipe time and time again!
Oh wow!! ricotta and garlic chips sound wonderful! I am glad you tried this recipe!
Great sauce for manicotti too. I replaced the Italian seasoning with a mixture of mostly fenugreek leaves, and a little basil, and oregano, then added more pepper flakes and a little curry powder for a slight Indian twist. Ever since trying the lasagna on your site(the Indian style one) I have enjoyed putting an Indian spin on Italian stuff. My kids and I are not usually fans of Italian fare, but my husband is. The Indian fusion is something we all seem to be able to agree on as delicious . Another winner
Glad to know it, Jessica, I am happy you are trying Indian flavors.
Making it right now, my kitchen smells amazing. Very good recipe.
Wow… Roasted pepper sauce is my favorite, specially on pasta and pizza too.
Loved the color and texture! Beautiful💕
Thank you, Dhwani! We love it too!
