Tired of plain old tomato sauce?  Well, this red pepper sauce is the perfect swap.  It’s still tomatoey and delicious, but with a slightly different flavor profile.  This sauce is a bit sweeter and richer than traditional marinara.  The roasted red peppers add that perfect punch of flavor. It’s perfect for summer pasta dishes!

What Do I need to Make Vegan Roasted Red Pepper Sauce?

You don’t need much to make this sauce.  Just a big old soup pot, an offset spatula, and some commonly found ingredients.  (That you probably already have)


  1. Onions
  2. Olive or Safflower Oil
  3. Garlic
  4. Red Pepper Chili Flakes
  5. Roasted Red Peppers
  6. Tomatoes
  7. Basil
  8. Parsley
  9. Oregano

Fresh Basil and parsley are always easy to find.  If you can’t find fresh oregano, then use 1 teaspoon of dried oregano instead.  I prefer to use fresh herbs to make this vegan sauce, but if you don’t have them on hand, you can use dried herbs instead.

PRO TIP: Just remember that 1 tablespoon of fresh herbs is always equal to 1 teaspoon of dried herbs.  So just keep this calculation in mind when using dried herbs instead of fresh.  So for this recipe if you use dried herbs here are the calculations:

Fresh Herbs to Dry Herb Calculation

  • Parsley – 1/4 cup = 4 Tablespoons = 4 tsp of dried parsley
  • Oregano – 1 Tablespoon = 1 tsp dried oregano
  • Basil – 3 Tablespoons Fresh = 3 tsp dried basil

How to Make Healthy Roasted Red Pepper Pasta Sauce

This sauce is so easy to make, you may never need to use jarred sauce again!

Step 1: Heat oil in a 4 quart soup pot like this one.  Add chopped onions and saute them for 5 minutes.  (Or until they’re translucent and soft).  Next, add the chopped garlic and red pepper chili flakes.  Saute for another one minute.  This will help bloom the spices.

Step 2: Pat the roasted red peppers dry and chop them.  Add them to the pot and stir to combine the ingredients.  Next add the tomatoes.  Bring the sauce to a boil and then lower the heat so that the sauce is simmering (little bubbles).  Allow it to cook partially covered for another 30 minutes.

Step 3: Transfer the soup to a food processor.  Add the parsley, oregano and basil.  Pulse until the soup is slightly chunky, but smooth.  Return it to the pot to reheat and enjoy!

Make Creamy Roasted Red Pepper Pasta Sauce Instead

If a chunky sauce just isn’t your style, fear not!  You can make this sauce silky smooth and so creamy no one will ever believe it’s vegan! Just blend it in a high speed blender instead.  I recommend the Vitamix.  I use the Vitamix for tons of my recipes like smoothies and soups.  Like this Pineapple Banana Smoothie.

How to Serve this Sauce

My favorite way to serve this sauce is in Healthy Baked Eggplant Parmesan.  It’s so rich and tasty you’ll never know that this version of eggplant parmesan is actually healthy and detoxifying.
