Stuffed Bell Pepper with Mexican Orzo Bake
Orzo instead of rice. That's the move here. The wheat pasta picks up the cumin-paprika-chili seasoning in a way rice never does, and it holds its texture through the second bake. Ground beef, corn, and diced tomatoes round out the filling. Cheddar melts on top.
43g of protein packed into a single roasted bell pepper. The pepper goes into the oven twice: once empty to soften, once stuffed to let everything fuse under a bubbling cheese layer. 15 minutes of your time, about 35 in the oven.
Ingredients
- orzo 84 g
- bell pepper 1
- olive oil 30 ml
- red onion 0.25
- garlic 5 g
- corn 56 g
- 96% lean ground beef 84 g
- paprika 2 g
- cumin 2 g
- chili powder 1 g
- diced tomatoes 196 g
- cheddar cheese 42 g
Method
-
Preheat oven to 200°C. Cut the top off the bell pepper, remove seeds and white parts. Place in an oven dish and bake in the oven until done, about 25 minutes.
-
Meanwhile, cook the orzo according to package directions. Drain.
-
Heat the olive oil in a pan over medium heat and sauté the red onion and garlic for 2 minutes.
-
Add the corn, ground beef, paprika, cumin, and chili powder and cook, stirring, until the ground beef is browned, 4–5 minutes.
-
Add the diced tomatoes and season with salt and pepper. Stir in the cooked orzo.
-
Fill the bell pepper with the orzo mixture, sprinkle the cheddar cheese on top, and bake for 10 minutes.
-
Serve immediately.
Roast the bell pepper until the skin just starts to wrinkle and gives slightly when pressed. Too firm and it won’t absorb the tomato juices during the second bake. Too soft and it collapses under the filling.
Sautéing garlic and red onion directly with wheat-based pasta does more than build flavor. Research by Platel and Srinivasan found that sulfur compounds in garlic and onion increase iron and zinc bioaccessibility from food grains by up to 70%. In this recipe, that interaction happens at Step 3, where the orzo meets the garlic and onion in olive oil.
Platel & Srinivasan · DOIWhy This Works
Behind this recipe
Can I swap the orzo for rice?
Yes, white rice works. The texture changes though. Orzo is wheat semolina, so it absorbs the cumin-paprika seasoning differently and holds its shape through the second bake better than most rice varieties. If you switch, rinse the rice well and adjust cooking time.
Why roast the bell pepper before stuffing it?
The first 25-minute bake softens the pepper walls so they hold the filling without cracking. Skip this step and the pepper stays rigid, which means the tomato juices from the filling won’t absorb into the pepper during the second bake. You want the pepper to be a vessel, not a container.
Does cooking the beef twice reduce the protein?
No. Sautéing and then baking changes protein’s 3D shape (denaturing), which actually improves digestibility. The amino acids your body uses to build and repair muscle survive both cooking rounds intact. Heat changes structure, not nutritional value.
Is 973 kcal a lot for one meal?
It comes down to your full day. This meal delivers 43g of protein, roughly a quarter of what research identifies as optimal for body composition at the higher end of the range. If you eat three to four meals a day with a target above 2,000 kcal, this fits. If you’re in a deficit, consider splitting it across two sittings.
