Quinoa And Beef Stuffed Peppers With cottage Cheese

Save to Find It Later!

Stuffed peppers used to be one of those dishes I’d avoid because they always came out watery or bland. But once I started roasting the peppers first and making a creamy, protein-packed filling with beef, quinoa, and cottage cheese—I was hooked. These beef and quinoa stuffed peppers are now a weeknight favorite. They’re hearty, satisfying, and actually taste just as good the next day.

What makes these work is all in the layering. They’re filling without feeling too heavy, and the combo of quinoa and cottage cheese makes them packed with protein. They’re also super easy to prep ahead—you can make the filling in advance and just assemble when you’re ready.

Tips to make your stuffed peppers better

• Always roast your peppers before stuffing! It keeps them from turning soggy and gives you a better texture overall.
• Rinse your quinoa well before cooking. If you don’t, it can have a slightly bitter or soapy taste.
• Use lean ground beef (I go with 5%) so the filling isn’t greasy, especially since you’re adding cheese.
• You can season your beef and sauce while cooking, depending on what flavors you like—smoked paprika, chili flakes, or garlic powder all work well.

Ingredients

• 3–4 bell peppers, halved and seeds removed
• ½ cup dry quinoa (about 85g / 3 oz), rinsed
• 250g (about 9 oz) lean ground beef (5% fat)
• 1 cup tomato sauce or 1 can (400g / 14 oz) peeled tomatoes
• ½ cup cottage cheese (about 120g / 4.2 oz)
• ½ cup shredded cheese (about 50g / 1.75 oz), for topping
• Salt and pepper, to taste

Alternative Ingredients

You can swap the beef for ground turkey or chicken for a lighter version, or use lentils or black beans for a vegetarian take.

Instead of cottage cheese, ricotta or plain Greek yogurt also works if you still want that creamy, protein-rich filling.

If you don’t have tomato sauce, use crushed tomatoes or even a jar of pasta sauce—just adjust seasoning as needed.

Step 1: Roast the Peppers

Preheat your oven to 190°C (375°F). Wash your bell peppers, slice them in half lengthwise, and remove all the seeds and inner membranes.

Place them cut side up on a baking tray and roast for 30 minutes. This step helps dry them out so they hold the filling better later.

Step 2: Cook the Quinoa

While the peppers roast, rinse your quinoa thoroughly under cold water. Cook according to package instructions, usually about 15 minutes in simmering water, then set aside.

Step 3: Cook the Beef

In a separate pan, cook your lean ground beef over medium heat until browned and fully cooked. Break it apart with a spatula as it cooks and season lightly with salt and pepper.

Step 4: Make the Filling

Once the beef is cooked, lower the heat and add in the cooked quinoa and your tomato sauce or peeled tomatoes. If using whole tomatoes, break them up with a spoon as they simmer.

Stir in the cottage cheese to make the mixture creamy and protein-rich. Let everything cook together for a few minutes so the flavors combine.

Step 5: Fill and Top the Peppers

Remove your roasted peppers from the oven. Spoon the beef and quinoa filling into each pepper half, packing it in well. Top each one with shredded cheese.

Step 6: Bake Again

Return the stuffed peppers to the oven and bake at 190°C (375°F) for another 15 minutes, or until the cheese is melted and slightly golden.

How to Conserve the Recipe

These stuffed peppers are perfect for meal prep. You can store them in an airtight container in the fridge for up to 3 days. They reheat really well in the oven or microwave—just cover them loosely if you’re using the microwave so the cheese doesn’t get rubbery.

You can also freeze them after baking. Let them cool completely, wrap each pepper half in foil or store in a freezer-safe container. To reheat from frozen, bake at 180°C (350°F) for about 25–30 minutes, or until hot throughout.

Different Ways to Serve This Dish

These beef and quinoa stuffed peppers are a full meal on their own, but you can easily bulk them up with sides. I like serving them with a light side salad or some roasted vegetables if I’m feeding a crowd.

You can also slice them up and serve over rice or inside a wrap for a different twist on leftovers. If you’re going low-carb, just enjoy them as is—they’re already hearty, rich in protein, and totally satisfying.

They’re also great for dinner parties. Prep everything ahead of time, then just bake and serve when your guests arrive. Simple, flavorful, and always a hit.
