Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Provides the main savory body and fat that carries flavor through the filling.
- Bell peppers
- Form the edible vessel, softening as they cook and adding mild sweetness.
- Onion
- Softens and turns sweet as it cooks, building the base aroma of the filling.
- Rotel tomatoes
- Add moisture and acidity that keep the filling saucy and balance the rich beef.
- Parmesan cheese
- Adds salty, savory depth and browns on top for a golden finish.
- Bread crumbs
- Absorb liquid in the filling and form a crisp, browned topping.
The step that matters
Partly cook the peppers in the filling. Peppers that are not softened before baking can stay firm and bitter. Cooking them until somewhat tender in the beef mixture lets their flesh soften fully in the oven without overcooking the filling.
