  2. Remove the seeds from the peppers.

Stuff and bake

  1. Stuff the peppers with the mixture.

  2. Place a small piece of butter on each pepper.

  3. Bake in a moderate oven at 350°F (175°C) until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Bacon
Renders fat that carries flavor and browns the filling as it fries.
Lettuce
Wilts when cooked, releasing moisture and adding a soft, leafy texture to the filling.
Tomato
Adds moisture and a bright acidity that balances the rich bacon.
Onion
Softens and turns sweeter as it fries, adding aroma to the filling.
Peppers
Form the edible shell that holds the filling and soften as they bake.
Butter
Adds richness and fat that helps the tops brown in the oven.

The step that matters

Bake until cooked through. Raw pepper walls stay firm and crisp, so the peppers need enough oven time for heat to soften them while the filling cooks through.

Swap the lettuce

How well each one fits the dish's main ingredients (tomato, onion, pepper, butter):
