  • More Tomato Flavor. Include tomato paste for a more robust tomato flavor.
  • If preferred, replace the cilantro with fresh parsley.
  • Instead of ground beef, feel free to use ground turkey or ground chicken.
  • Use your preference of white or brown rice for this easy recipe.
  • If you’re not a fan of either green, yellow, or red bell pepper, use whichever variety is your favorite.

Storage and reheating tips

  • Store the leftover casserole in an airtight container for up to 5 days in the fridge.
  • I don’t suggest freezing rice dishes because the consistency of the rice, when thawed out, is a bit too soft. If you left the rice out, you could freeze the dish and add the rice before serving.

Frequently asked questions

How long does it take to soften bell peppers on the stove?

After about 7 minutes of cooking, slice peppers in a hot pan or pot, they should be soft and ready to eat unless you prefer them extra soft or overcooked.

What can I do with lots of bell peppers?

Peppers are versatile, giving you many options when figuring out what to do with an excess. You can always stash some away in the fridge or freezer to make dishes later, like potato and pepper soup, Red Pepper and Bacon Bruschetta, Roasted Red Pepper and Artichoke Tapenade, or Pepper Steak Stir-Fry.

Which is healthiest — red, green, yellow, or orange bell peppers?

The red bell pepper contains more antioxidants because it has been ripened for longer. All are tasty, but the further from green, the more nutritional value.
