The creamiest roasted red pepper sauce packed with hidden veggies...and all without any nuts! THIS is what dreams are made of.
Imagine it's a cozy night in. You just opened a bottle of wine, you have your favourite music playing and a bowl of creamy vegan red pepper pasta is waiting for you. This sauce is seriously one of the most amazing things I've made. I swear I'm not exaggerating it tastes amazing but it's also healthy. It's creamy, it's vegan, it's packed with veggies and you need it ASAP.

When I was younger I used to be a VERY picky child. Pasta was pretty much the only food I would eat until I was 10. But honestly I think I was on to something. What's not to love about pasta? Want an easy dinner? Make a bowl of pasta with tomato sauce. Want a fancy date night meal? Make a homemade sauce. Want a food to comfort you after a hard week? A bowl of creamy pasta is there for you. PASTA can do it all.
Some pasta sauces can be so heavy though and as much as I love past sometimes you just want a lighter version. Introducing: this creamy vegan roasted red pepper sauce. It's made from a base of roasted red peppers and sun dried tomatoes mixed with non-dairy milk and some spices for extra flavour. So you get all the same great thick creaminess we love about a good pasta sauce but there is no heavy cream. Oh and it also only takes less than an hour to make from start to finish. Now that's a win in my books.
Looking for your next date-night meal to wow your loved ones? this is IT. Don't believe me? Try it for yourself.

Roasted Red Pepper Sauce Recipe
Ingredients

Red Bell Peppers. These are the base of the sauce! Roast them until soft and lightly charred, then blend until smooth. I love roasting my own because it feels extra satisfying to make a recipe fully from scratch, but jarred roasted peppers work just as well. Just drain any excess oil before blending. If using jarred peppers, you can skip roasting the garlic and add it straight into the food processor.
Sun-Dried Tomatoes. Sun-dried tomatoes add depth, saltiness and a rich roasted flavour. They're one of my favourite ingredients to add to sauces because they instantly make everything taste more elevated.
Nutritional Yeast. A vegan-friendly flavour booster packed with B vitamins, including plant-based B12. It gives the sauce a subtle cheesy, nutty vibe. If you're not vegan, parmesan works as a substitute!
Cornstarch. The simple secret to getting that perfectly thick, creamy sauce. If you don't have cornstarch or need an alternative, arrowroot starch or another sauce thickener will work just fine.
Milk. Any unsweetened, unflavoured milk works: oat, almond, soy or dairy. Just make sure it's unsweetened so the sauce doesn't accidentally taste like dessert.
Basil. I usually use dried basil because it's affordable and always in my pantry, but if you're going for more of an Italian-style flavour, fresh basil is amazing. About ¼ bunch, chopped, is perfect.
Pasta. Use your favourite pasta shape! Chickpea or whole-wheat pasta is a great option if you want to add extra protein and fibre.

Nimue says
This was really good!! I used thyme and oregano bc no basil on hand, and I topped with oyster mushrooms that I had sautéed in the sun dried tomato oil. Gosh this was really good. I would say I used 1C less pasta to sauce ratio for a creamier pasta .
