My mom used to make a delicious and healthy pasta recipe many, many years ago. The sauce was simply red peppers sautéed with onions in chicken broth then it was pureed and with heavy cream. She used to make pasta with grilled chicken and snow peas with this sauce and it was a delicious dinner.
Well lately I have been LOVING zucchini noodles and thought I’d try my own version by using roasted red peppers and garlic for my healthy roasted red bell pepper sauce that used with zucchini noodles and chicken breast. I made sure to make my red pepper sauce low carb so it had only 1.7g net carbs for 2 tablespoons. It’s also a delicious keto condiment and there is a variety way you can use it.

What makes this creamy sauce healthy.
Bell peppers are a nightshade vegetable and while some people have trouble with them my family does not. My husband grows all kind of peppers and we eat them a lot. I’m talking everyday.
Bell peppers are low in calories, high in vitamin C and other antioxidants and they are low carb. In 100g of chopped peppers there are only 3.9g net carbs and 31 calories. Check out this post on the benefits of peppers for more info.
This red pepper sauce is healthy to me because it’s simply peppers, garlic, olive oil and cream which combined makes for a delicious low carb sauce. It’s also a nice change of pace from marinara sauce for pasta, especially if you have trouble with tomatoes. My family loves it and it’s so simple.
Recipe ingredients and substitutions.
The simple ingredients I used were red bell peppers, fresh garlic, olive oil, salt and heavy whipping cream. I also sometimes add some hot red pepper flakes but that’s because my husband makes his own and they are awesome. You could add some fresh basil leaves for garnish or even a sprinkling of parmesan cheese if you are making this as a pasta sauce.
- red bell peppers – You really need to use red peppers and not green in this recipe. You can also use yellow or orange ones as they have a sweet tastes too. But the green are too bitter.
- heavy whipping cream – This is necessary to give this sauce a creamy flavor. You could also try some cream cheese as a substitute. And if you are dairy free you can try coconut cream or coconut milk but it will have that added coconut flavor so be forewarned.
- fresh garlic – You roast the garlic along with the pepper so I would not substitute with garlic powder.

How to make roasted red bell pepper sauce.
Step 1: Preheat oven to 400°F. Spray a baking sheet with nonstick cooking spray and set aside.
Step 2: Roughly chop the bell pepper into uniform size chunks and add to the baking sheet. Also add the garlic cloves and then pour the olive oil over top. Sprinkle the salt and pepper and then mix with your hands or large spoon.
You can also add everything to a bowl and mix then pour into the prepared baking sheet.

Step 3: Place in the preheated oven and roast for 30 minutes until the roasted red peppers are tender and just turning brown. Watch that you don’t burn them.

Step 4: Let the roasted red peppers cool for a few minutes then add to a high speed blender along with the heavy cream. Blend until the puree is smooth and creamy and that’s all there is to it!
You could also use an immersion blender or food processor but the high speed blenders make it smoother in my opinion.

Pour the sauce into a bowl and use as a condiment or sauce. Store leftovers in an airtight container. I used it over some chicken breast and zucchini noodles (see below). If you eat it like this you can add a sprinkling of parmesan cheese on top for even more flavor.

Ingredients

Preheat oven to 400° F. Spray a baking sheet with nonstick cooking spray and set aside.

Next add vegetables to a high speed blender along with the heavy cream. Blend on high until the puree is smooth and creamy. Taste and see if you need a bit more salt. I always go a little light so you can add more if you want at this stage. Sometimes I add some chili flakes because I like the added heat but that is optional.

If you wish to have a thinner sauce, add a bit more cream, water or chicken broth. Spoon into an airtight container and use as a pasta sauce, condiment or dipping sauce. Tastes great on chicken, pork loin, fish or shrimp too.

Why do people rate a recipe before trying?? I made this a few times and love it. Please actually make it before rating it
Riverlandlass says
This sounds lovely, but a question:
How long can this be kept in the fridge if you make a large batch, or will it freeze successfully?
Thanks
Denise says
Hi, I think it would last for 5-7 days in the refrigerator and while I have not tried it, I think it would freeze ok. If it seems to separate when thawed just blend it in the blender again. Sorry I’m not much help but I hope you like it!
Michal con delight says
Looks really delicious! Do you by any chance have your mother’s recipe for the pasta and grilled chicken, sounds so good!
Denise says
HI Michal, She would make fettuccine or linguine and at the end throw in some snow peas. In the meantime she would pan fry a few chicken breasts and cut them up. Lastly she would mix all of these together with the sauce. It as really quite good and we ate it often.
