Vegan Roasted Red Pepper Pasta

This vegan roasted red pepper pasta recipe is so creamy, comforting and delicious! 

Made with oven-charred red peppers, red onions and garlic, blended with creamy coconut milk and tomatoes.

Add some basil, nutritional yeast (for a subtle cheese flavor) and smoked paprika and you have a super flavorful, unique and irresistible pasta recipe.

This is a great way to switch things up, and has much deeper and richer flavors than normal tomato sauce.

Making your own pasta sauce is always a good idea – the taste is stronger and more fresh than anything you can buy in a jar.

This recipe is also very budget friendly and has very simple, healthy ingredients.

The char from the roasted veggies adds even more flavor and a hint of smokiness.

I absolutely love oven-roasted veggies, the flavor is so much tastier than any other way of cooking them!

The process of making this pasta sauce is also so simple – you just chop the peppers, onion and garlic into thick pieces and toss them in a bit of oil, salt and pepper, then leave them to bake until they are lightly charred and tender!

Then you just blend it with the other ingredients and toss in some cooked noodles.

The sauce is also thickened ever so slightly with just a sprinkle of flour, making this dish so comforting and hearty.

Add these to a blender with the coconut milk and tomato paste and blend until smooth!

In a pan, heat some oil and add the flour, whisk it constantly for a minute while it bubbles and cooks, it should get a subtle light golden color during this process.

Toss in your roasted pepper sauce along with the seasonings and mix until smooth, continuing to cook on a low simmer for at least 5 minutes.

Add to a bowl along with the cooked fettuccine and toss, then you can serve with another light sprinkle of basil!

Dairy-Free Red Pepper Sauce Recipe

I just love this thick and delicious red pepper sauce, it has so much flavor and I just can’t get enough of it.

Many red pepper sauces have a good amount of dairy in them, but this sauce is perfectly thick and creamy thanks to the coconut milk, nutritional yeast and the dash of flour.

You could also definitely add some mushrooms or zucchini to this dish, but I loved it just as much plain.
