Do you have to cook the peppers before stuffing them?
No, not for this method. Baking in sauce steams them from the bottom and sides, so they turn tender without pre-boiling. If you like very soft peppers, you can pre-bake the hollowed peppers for 10 minutes while you make the filling.
What rice is best for stuffed peppers?
Long-grain white rice is the easiest, but any cooked rice works: jasmine, basmati, brown rice, or even cauliflower rice. For reference, about 1 cup uncooked rice makes roughly 2 cups cooked, depending on the variety. If you use brown rice, make sure it is fully cooked before mixing it into the filling.
How do you keep stuffed peppers from being watery?
Two things help: drain excess grease from the meat, and do not overdo the liquid in the filling. The sauce belongs mostly in the pan, not inside the pepper. Also, let the peppers rest 5 to 10 minutes after baking so the filling sets up.
Can I make these vegetarian?
Absolutely. Swap the beef for 1 to 2 cans (15 ounces each) black beans or pinto beans (rinsed and drained), or use a plant-based ground. Add chopped mushrooms for extra savory depth, and if the mixture looks a little short, stir in a bit more cooked rice or an extra handful of cheese to keep all 6 peppers generously filled.
What cheese melts best on top?
Mozzarella is classic for that stretchy pull, but cheddar brings more flavor. Monterey Jack, provolone, or a mozzarella-cheddar blend all work.
How do I know they are done?
The peppers should be tender when pierced with a knife, and the filling should be hot throughout. For extra certainty, check the center of the filling with a thermometer and aim for 165°F.
