Roasted Bell Peppers in Sweet Onion Marinade

Bell Peppers in Sweet Onion Marinade – sweet peppers that are full of flavor borrowed from the marinade of vinegar, garlic and sweet onion.Roasted bell peppers in marinade topped with fresh greens in a white bowl.


Roasted bell peppers in a glass bowl.I posted a recipe for the mini bell peppers in the past, but now wanted to add a recipe for these meaty and delicious Bell Peppers in Sweet Onion Marinade as well. While the mini peppers win in presentation, I think regular sized peppers would have to win in taste. They have more flesh to them and when you bite into one, they have a different mouth feel then the baby ones.

I served these Bell Peppers in Sweet Onion Marinade with baked yellow potato, drizzled with some salted butter and sprinkled with cheese. I have been trying to stay away from starchy foods and instead replace my diet with fresh veggies and some protein. This evening I really wanted a potato so, I skipped the meat and had myself a delicious potato and Bell Peppers in Sweet Onion Marinade dinner.

Calories: 162 kcal
Prep Time: 30 minutes
Cook Time: 30 minutes
Total Time: 1 hour
Servings: 4 servings


  • 4 bell peppers various colors
  • 1 large sweet onion
  • 5 tbsp vinegar
  • 3 tbsp olive oil
  • 1 tsp salt to taste
  • 1 clove garlic pressed
  • 3 tbsp chopped parsley


  1. Roast washed bell peppers in the oven at 350°F, rotating on each side until the skin puffs up and peppers brown up slightly.

  2. Remove into a dish and cover with lid or plastic wrap. Let sit for 10-15 minutes (to make the peeling easier).
  3. Peel and chop the onion. Rinse it under cold running water to remove any bitterness.
  4. Add 1 tsp salt, 5 Tbsp vinegar, 1 minced garlic & 3 Tbsp oil, mix & set aside.

  5. Once the peppers are cool enough to handle, peel each pepper removing the skin, but leaving the stem(optional) (for presentation only).
  6. Line a dish with 1/2 the prepared onions, place the peeled peppers on top. Cover with the rest of the onions. Let sit for 1-2 hours, refrigerated.
  7. *The peppers can be eaten right away, but are better once they have marinated and absorbed some of the aromatic onion and the vinegar.
