Roasted Red Pepper Sauce with garlic, onion and crushed tomatoes – Serve over pasta, chicken, fish or veggies and enjoy! Gluten Free + Paleo + Vegan
Originally published May 14, 2015 – Updated August 17, 2018
For those times when you really want a red sauce but you don’t want the same old tomato dish – this roasted red pepper sauce is where it’s at.
How to Make: Roasted Red Pepper Sauce
Start out by prepping your red peppers: cut them in half and then remove the seeds and stems as you can see in the pictures above (photo 1 & 2).
Move on the arrange the red peppers on a baking sheet along with the quartered red onion and garlic cloves. Brush everything with a little oil and then pop it in the oven to roast for about 25 minutes.
There are two main reasons that you’d want to get rid of the skin:
-
- The skin is pretty tough and doesn’t easily break down. You’d end up with little bits of hard skin all throughout your sauce.
- The skin has a strong, bitter flavour that can end up overpowering everything else in the dish.
Fortunately, once roasted the peppers become extremely easy to peel. Just pinch the wrinkly red pepper skin and pull away and it should peel back fairly easy.
When you’re all set just add the peppers, onion and garlic to a blender or food processor along with with your remaining ingredients and blend until smooth or mostly smooth – depending on how chunky you want your sauce.

Can this sauce be made without the tomatos?
Hi Lori! I haven’t tried this without the tomatoes so I can’t say for sure but I do think it would work. You will probably need to increase the amount of red peppers though because the tomatoes do add quite a bit of bulk
Made this tonight, but had no canned tomatoes so pureed some slightly soft, fresh tomatoes after simmering with a little water, honey and sun-dried tomato paste, followed the rest of the recipe exactly and well what can I say totally delicious and will be a firm favourite from now on, I’m from Scotland and just came across your site and am very pleased I did, thank you, simply stunning recipe
Thanks
Helen
Hi Helen – I’m so glad you enjoyed it! That honey and sun dried tomato paste sounds lovely! I need to try that myself!
Looks delicious! Could I use roasted red peppers from a jar?
Thanks Kris! That’s totally fine!
