Ingredients And Substitutions
Though traditional stuffed peppers are a mix of cooked rice and ground beef (or ground turkey), these gluten-free ones have a bit of a twist.
- Cooked quinoa: having quinoa cooked in the fridge is a sure-fire way to make meal prep easier and is actually one of my favorite tips for gluten-free meal prep. Save yourself the time and have it ready.
- Bell peppers: any color will work but try to get peppers that are larger, this way you can fill them right up.
- Veggies: mixed into the gluten-free stuffed peppers are mushrooms, zucchini, and asparagus. However, any of your favorite vegetables will work here. Chop them all finely so that they cook evenly and don't take up too much room.
- Garlic: the perfect addition whenever you sautee something.
- Olive oil: used to saute the seasonings and you don't use much. Any neutral flavored oil will work.
- Red pepper flakes: responsible for the spicy kick on these stuffed peppers! Adjust this to your personal preference.

But What About The Protein?
Quinoa is one of the few plant-based foods that contain all essential amino acids. Meaning, you don't need to add anything to the stuffed peppers if you don't want to.
That said, if you feel the need to step up your protein, you can easily serve the peppers on the side of something larger, or mix in any of the following:
- Leftover Dutch oven chicken
- Leftover spiced ground beef
- Dairy-free scrambled eggs
- Chopped Italian sausage
How To Make Spicy Gluten Free Stuffed Bell Peppers

Step 1: Saute the garlic and red pepper flakes in oil until crackling.

Step 2: Mix in the veggies and cook until soft before adding in the cooked quinoa.

Step 3: Prepare your peppers by removing the seeds and stem and placing them in a baking dish.

Step 4: Stuff the peppers and bake in the oven.
Expert Tips To Make It
Serve the bell peppers either as whole peppers stuffed standing up (in which case flatten the bottom as much as possible, or sliced in half and stuffed on their sides (thus doubling the servings).
Top the gluten-free stuffed peppers with sliced green onions, kimchi, avocado, or salsa for additional flavor. To make the stuffed peppers paleo or whole30 approved, use cauliflower rice in place of quinoa.
