Method of preparing the stuffed peppers in the slow cooker

Timing

Serving: 6

Preparation time: 20 minutes

Cooking time: 8 hours

Total time: 8 hours 20 minutes

Ingredients

• 6 bell peppers

Stuffing

• 500 grams ground beef
• 1 onion, diced
• 2 tbsp crushed garlic
• 2 tbsp tomato paste
• 2 tbsp Worcestershire sauce
• 1 tbsp dried oregano
• 2 tbsp chopped parsley
• 1/2 cup cheddar cheese, shredded
• 1 cup cooked rice
• 1/4 tbsp ground black pepper
• 1 tbsp salt
• 425 grams marinara sauce

Step by Step Instructions

1. Cut the tops off the bell peppers and remove the seeds and inner membranes. Rinse and set aside.
2. In a mixing bowl, combine the diced onion, ground beef, garlic, tomato paste, Worcestershire sauce, cheddar, parsley, oregano, salt, pepper, and the cooked rice. Mix until evenly combined.
3. Stuff each bell pepper with the beef and rice mixture, pressing gently to fill.
4. Arrange the stuffed peppers upright in the slow cooker. Pour the marinara sauce around the peppers—avoid filling the peppers with sauce to prevent a soggy filling.
5. Cover and cook on low for about 8 hours, or until the beef is fully cooked and the peppers are tender. For a faster option, cook on high for 3–4 hours.
6. When done, top with extra cheese if desired, and serve warm.

Recipe tips

• Use lean ground beef or drain excess fat before combining to avoid a greasy slow-cooker base.
• Always use cooked rice in the filling—uncooked rice won’t cook through in the slow cooker and will remain hard.
• Pour sauce around the peppers rather than into them to keep the filling from getting too wet.
• Substitute beef stock or a different pasta sauce for marinara if you prefer a different flavor.
• To shorten the cook time, set the slow cooker to high; the dish will be ready in three to four hours.

Why slow cooker stuffed peppers are healthy

Slow cooker stuffed peppers offer several health benefits. The peppers themselves are rich in vitamins, minerals, fiber, and antioxidants while the lean meat and rice provide protein and energy. Highlights include:

High in Vitamin C

Bell peppers are an excellent source of vitamin C, which supports immune function, collagen production, and iron absorption.

Rich in Vitamin A

Peppers provide vitamin A, which supports vision, cell growth, and healthy organ function.

Antioxidant support

Peppers contain antioxidants such as beta-carotene, flavonoids, and luteolin, which help protect cells from oxidative damage and support overall health.

May reduce disease risk

The nutrients in peppers—like vitamin C and various carotenoids—are associated with lower inflammation and reduced risk for certain chronic conditions.

Low in calories and filling

Stuffed peppers can be relatively low in calories while high in fiber and protein, which helps promote satiety and support weight management.

Suggested toppings and sides

You can customize toppings to match your taste. Popular options include:

• Extra shredded cheese (cheddar, mozzarella, or Parmesan)
• Greek yogurt or sour cream
• Salsa or hot sauce
• Enchilada sauce or avocado slices
• Fresh cilantro and a squeeze of lime

Serve with a side salad, rice, or mashed potatoes for a complete meal.

Storage and reheating

Store leftover stuffed peppers in an airtight container in the refrigerator for 3–4 days. Reheat in the microwave or oven until heated through. You can freeze portions for 2–3 months—thaw completely before reheating.

Frequently asked questions

What rice should I use?

Both white and brown rice work well. Leftover cooked rice is ideal for texture and convenience. Avoid using raw rice in the filling.

Why should I eat stuffed peppers?

They combine vegetables, protein, and grains into a balanced, nutrient-rich meal that supports immunity, digestion, and overall health.

What to do with leftovers?

Leftovers reheat well for lunch or dinner. Store in the refrigerator and warm in the microwave or oven; flavors often improve after a day.

Precautions when cooking

• Observe cooking times to avoid overcooking, which can reduce nutrient levels.
• Wash produce and hands thoroughly before preparing the recipe.
