Do I need to cook the peppers before stuffing them?
You do not have to, but I recommend a quick pre-bake so the peppers get tender at the same time the filling heats through. If you skip it, you will likely end up with hot filling and crunchy peppers. Your goal is knife-tender peppers (a paring knife should slide in easily).
What kind of rice is best?
Any cooked rice works. Long-grain white rice stays the most distinct and fluffy. Brown rice is great too, it just has a chewier bite. This is also a good place to use leftover rice from takeout night.
Can I make these ahead?
Yes. Assemble the peppers and keep them covered in the fridge up to 24 hours. Bake when ready. Add 10 to 15 minutes to the covered bake time since everything starts cold, and bake until the filling is hot in the center (165°F if you want to be exact).
How do I keep the filling from being dry?
Two things: do not skimp on the sauce in the baking dish, and keep the filling a little saucy before stuffing. If it looks perfect in the skillet, it will look dry after baking. Add a splash of broth or water (or a bit more tomato sauce if you have it) if needed.
Can I make them without meat?
Absolutely. Swap the beef for a can of drained black beans or pinto beans, or use chopped mushrooms. Add an extra pinch of salt and a little more smoked paprika to keep the flavor bold. Also note: Worcestershire often contains anchovies, so skip it or use a vegetarian version.
What can I use instead of Worcestershire?
If you do not have it, use 2 teaspoons soy sauce plus 1 teaspoon vinegar (apple cider or red wine). You can also just leave it out. The tomato paste and smoked paprika still do a lot of heavy lifting.
