Which peppers are best for roasting?

You can roast whatever peppers you wish. We chose Krimson Lee peppers because they are a roasting type of pepper and we grow them in our greenhouse.

Krimson Lees have some heat until they are seeded and cooked, then the heat disappears into an intense, sweet pepper flavor. Pasilla peppers would work as well, or even sweet bells, but the flavor may be less intense.

How can I use peppers in cooking?

Fresh peppers are a wonderful addition to a variety of recipes, and can be enjoy raw, grilled, roasted, or stewed. Our roasted pepper sauce brings the flavor out by slow roasting our favorites in order to enhance the flavor before pureeing them into a delicious sauce.

Peppers can be used in salads, stuffed with pastas and meats, added to soups, and enjoyed raw for heat and crunch. You can also make your own fresh salsa with a variety of delicious peppers.

If you grow your own peppers here are just a few of our many recipes that use them up. We love peppers raw in salads like this Delicious Italian Chopped Salad, in stuffed peppers, and in sauces for meat marinades like our pork tenderloin dinner.

What is in a roasted pepper sauce?

Like a typical red pasta sauce there are a variety of ways you can make yours. From the choice of ingredients to the method of cooking the choice is ultimately up to you. However, most roasted pepper sauces include a variety of roasted peppers, vegetable broth or stock, aromatics such as onions and garlic, and a variety of Italian seasonings.

Once you have your base you can build on it and create a deeper flavor by adding basil and other fresh herbs. You can also make a creamier sauce by adding heavy cream, parmesan cheese and butter.

Why does my roasted pepper sauce recipe taste bitter?

If your roasted pepper sauce tastes bitter, it is likely because the peppers themselves have a bitter taste. Selecting the right peppers is important for not only the best flavor, but also the proper balance of acidity and heat.

Make sure you taste the peppers before you cook with them, and take the steps to properly prepare them for the sauce. Roasting the peppers, seasoning them properly, and de seeding them will all play a role in the final flavor of the roasted pepper sauce.

How do you roast Peppers?

Roasting peppers is a quick and simple way to bring a deeper flavor to your peppers as well as softening them and allowing the natural oils and flavors to release into your sauce. You can roast peppers on your stovetop if you have a gas stove with an open flame, or, if you are roasting a large batch you can assemble them on a baking sheet and broil them.

  • Cut your peppers down the side lengthwise.
  • Seed the peppers and lay them flat on a baking sheet.
  • Put them under your broiler on High for about 5 minutes.
  • Check the peppers after 5 minutes, they should be starting to cook, but not yet be blackened. Set the timer for another 5 minutes.
  • When the pepper skins are bubbling and blackened the peppers need to be removed from the oven
  • Transfer the peppers into an airtight container, immediately. The peppers will steam and the skins will loosen after about 10 minutes.
  • Remove the pepper skins and dice the peppers.

Roasted Red Pepper Sauce
Yield: 4 servings

Roasted Red Pepper Sauce

Cook Time: 30 minutes
Total Time: 30 minutes

Rich, thick as you like, roasted red pepper sauce. A flavorful condiment for your favorite pasta, meat or Mexican meal.


  • 4 large red peppers-roasted (about three 12 oz. jars)
  • 4 large garlic cloves (minced)
  • 1/2 Cup onion (chopped)
  • 1/4 Cup fresh basil (chopped)
  • 1 Tablespoon olive oil
  • 1/2 Cup sour cream
  • 1/2 Cup greek yogurt
  • 1/3 Cup parmesan cheese
  • 1/4 tsp. salt
  • 1/4 tsp. black pepper


Instructions for roasting Peppers: (optional)

  1. Turn oven broiler on high.
  2. Slice peppers in half and remove seeds. Place peppers (skin side up) on baking sheet.
  3. Put on middle rack in oven and set the timer to 5 minutes. Check the peppers. If not charred set the timer for another five minutes and check them in three. The skins need to bubble and be charred black in spots.
  4. Remove peppers from oven and put into an airtight container for about 10 minutes.
  5. Strip the skin from the peppers. They should remove easily if they are properly charred.

To make the roasted Red Pepper Sauce

  1. Dice all vegetables together and simmer in skillet until garlic and onion are translucent.
  2. Blend the pepper mixture with the sour cream and yogurt until smooth.
  3. Pour back in your skillet. Stir in cheese and let melt on simmer.
  4. Thicken the sauce by simmering, stirring occasionally until it reaches the consistency you desire.


Roasting Notes:

We offer the instructions for roasting your own peppers as an option. You can certainly buy jarred peppers for this recipe. However, if you grow your own peppers or buy a particular fresh pepper you can use our instruction to roast them.

Hot pepper Sauce:

You can easily make this into a hot pepper sauce with these adjustments:

  • Use jarred or fresh roasted HOT peppers. Anaheim, ghost peppers or other hot peppers are good choices.
  • If using fresh hot peppers leave the seeds in the hot peppers when cooking to really bring up the heat of this sauce.
  • Cook the peppers slightly less to really keep the heat in.


This recipe is very good as is. However, make it your own with seasonings of your choice.

Add your favorite seasonings to bring out the flavors of the peppers as you choose. For example Chipotle or cajun seasonings or hot asian spices.

This will give the sauce a more targeted cuisine flavor for whatever use you have in mind.

Can I make this a vegan roasted red pepper sauce?

Yes, with just a few changes in your ingredient selection you can make this a healthy roasted red pepper sauce that is vegan and even approved as a whole30 roasted red pepper sauce.

Use your favorite non dairy milk, like coconut or almond. Vegan yogurts can be used in place of the sour cream and Greek yogurt; while vegan cheeses can be added to enhance the texture, creaminess, and final flavor of the sauce.

It won’t be completely the same, but it will still give you a delicious, flavor filled vegan roasted red pepper pasta sauce.
