Can I prep them ahead?

Yes, you can. Uncooked stuffed peppers can be stored in an airtight container in the fridge up to 24 hours before cooking. To make sure everything is cooked through, add 1 or 2 minutes to the pressure cook time. Or you can prep the filling a day in advance and refrigerate in an airtight container or covered with plastic wrap.

Can I freeze cooked stuffed peppers?

It is possible, but not recommended as the peppers will change their texture. It is better to freeze uncooked stuffed peppers for a slightly better texture.

How long does it take to cook stuffed peppers in a pressure cooker?

For medium peppers, the active pressure cook time is 8 minutes. For large peppers, add an extra 1 to 2 minutes. Total time also includes the time for the pot to come to pressure and the pressure release.

What if I get a burn notice?

A burn notice usually means the sauce on the bottom is too thick or there isn't enough thin liquid. Add a splash of water or stock and ensure the peppers are sitting on a trivet so they aren't in direct contact with the sauce.

This method uses a pressure cooker to create tender stuffed peppers without the need for pre-baking. It is an efficient way to prepare a complete meal with a savory beef and rice filling in a short amount of time.

List of ingredients

4 medium bell peppers – any color, with tops removed and seeds cleared.
1 small onion – finely chopped for even distribution in the filling.
½ pound ground beef or ground turkey (220 grams) – provides the main protein base.
2 cups cooked rice (300 grams) – leftover rice works well here.
1½ tablespoons marjoram – divided between the filling and the cooking liquid.
1½ teaspoons salt – divided between the filling and the cooking liquid.
¼ teaspoon black pepper – for basic seasoning.
2 garlic cloves – minced finely.
3 tablespoons breadcrumbs – acts as a binder for the filling.
1 can tomato sauce (14 ounces/400 grams) – divided between the filling and the pot base.
½ cup water or chicken stock – used to create steam for pressure cooking.
½ teaspoon sugar – optional, used to balance the acidity of the tomato sauce.
1 teaspoon olive oil – optional, added to the sauce for richness.

step-by-step instructions

Prepare peppers: Rinse all the bell peppers. Cut off the tops and remove the internal membranes and seeds.
Mix filling: In a medium bowl, combine the finely chopped onion, ground meat, cooked rice, 1 tablespoon of marjoram, 1 teaspoon of salt, ¼ teaspoon of black pepper, minced garlic, breadcrumbs, and 4 tablespoons of the tomato sauce. Mix with a fork or by hand until the ingredients are well combined.
Stuff peppers: Fill each prepared bell pepper with the meat and rice mixture.
Prepare pot liquid: Pour the water (or chicken stock) and the remaining tomato sauce into the inner pot of a 6-quart Instant Pot. Stir in the optional sugar, the remaining ½ teaspoon of marjoram, a pinch of salt, and the optional olive oil.
Arrange peppers: Insert the trivet into the pot and place the stuffed peppers upright on top of the trivet.
Pressure cook: Lock the lid and set the steam release valve to SEALING. Press the PRESSURE COOK or MANUAL button and set the timer for 8 minutes on High Pressure.
Release pressure: Once the cooking time is complete, let the pressure release naturally for 5 minutes. Then, carefully turn the valve to VENTING to release any remaining steam.
Rest and serve: Let the peppers rest for a few minutes. Serve the peppers in the sauce or ladle the sauce over each portion.

Selecting the Best Bell Peppers

Using Red and Yellow Peppers for Sweetness

Red and yellow bell peppers have a higher sugar content than green ones. This results in a sweeter taste that complements the savory beef filling. These colors also remain vibrant after pressure cooking.

Using Green Peppers for a Bolder Taste

Green bell peppers are harvested earlier and have a slightly more bitter, grassy flavor. This profile is ideal for those who prefer a sharper contrast to the tomato sauce. Ensure they are firm to prevent them from becoming too soft.

Choosing Uniform Sizes for Even Cooking

Selecting peppers that are similar in size ensures they cook at the same rate. If you use a mix of medium and large peppers, the smaller ones may overcook while the larger ones remain firm. Stick to medium peppers for the 8-minute timing.

Grain Substitutions for the Filling

Substituting Quinoa for Extra Protein

Quinoa is a nutrient-dense alternative to white rice. Use pre-cooked quinoa in the same 2-cup quantity. It provides a slightly nuttier flavor and increases the overall protein content of the dish.

Using Brown Rice for More Fiber

Brown rice adds a heartier texture and more dietary fiber. Since brown rice takes longer to cook, it must be fully cooked before being added to the filling. Uncooked brown rice will remain hard during the short pressure cycle.

Preparing Cauliflower Rice for Low-Carb Needs

For a lower-carbohydrate version, replace the cooked rice with steamed cauliflower rice. Squeeze out any excess moisture from the cauliflower rice using a kitchen towel first. This prevents the filling from becoming watery during the cooking process.

Protein Alternatives and Ratio Adjustments

Using Ground Turkey for a Leaner Option

Ground turkey is an excellent substitute for ground beef. It reduces the total fat content while maintaining a similar texture. Use a lean turkey breast blend to avoid adding too much extra grease to the sauce.

Using Ground Chicken

Ground chicken is another lean alternative that pairs well with tomato sauce. Because chicken is milder than beef, you may want to slightly increase the amount of marjoram or garlic. Ensure the meat is mixed thoroughly with the binder.

Adjusting the Meat-to-Rice Ratio

The ratio of meat to rice can be adjusted based on preference. For a meatier filling, increase the beef to ¾ pound and reduce the rice to 1.5 cups. For a lighter filling, increase the rice and decrease the meat accordingly.

Flavor Enhancements and Variations

Adding Shredded Cheese for Richness

Adding shredded mozzarella or cheddar cheese can enhance the flavor. You can mix the cheese directly into the filling or sprinkle it on top of the peppers after the pressure release. If adding to the top, let the cheese melt for 2 minutes while the peppers are still hot.

Incorporating Spicy Jalapeños

To add heat, finely mince one or two jalapeños and mix them into the filling. Remove the seeds for mild heat or keep them for a spicier result. This pairs well with the sweetness of red bell peppers.

Using Italian Seasoning Instead of Marjoram

If marjoram is unavailable, Italian seasoning is a practical substitute. It contains a blend of oregano, basil, and rosemary that fits the flavor profile. Use the same quantity as specified for the marjoram.

Adding Fresh Parsley for Brightness

Adding two tablespoons of chopped fresh parsley to the filling adds a fresh, herbaceous note. Stir the parsley in at the end of the mixing process. This helps cut through the richness of the beef and tomato sauce.

Pressure Cooker Technical Tips

Preventing the Burn Notice

A burn notice occurs when thick liquids stick to the bottom of the pot. To avoid this, always use the trivet to keep the peppers elevated. Ensure there is enough thin liquid, such as water or stock, mixed with the tomato sauce.

Adjusting Timing for Large Peppers

Large peppers require more time for the heat to penetrate the center of the filling. Increase the pressure cook time by 1 to 2 minutes for jumbo peppers. This ensures the meat reaches a safe internal temperature of 160°F (71°C).

The Importance of the Trivet

The trivet is essential for creating a gap between the food and the heating element. Without it, the peppers sit directly in the sauce, increasing the risk of scorching. It also allows steam to circulate evenly around the vegetables.

Managing the Pressure Release Process

A natural release for 5 minutes prevents the filling from expanding and popping out of the peppers. Following this with a quick release prevents the peppers from overcooking in the residual heat. Always vent carefully to avoid steam burns.

Serving Ideas and Side Dishes

Pairing with Leafy Green Salads

A fresh garden salad with a light vinaigrette balances the richness of the stuffed peppers. Use mixed greens, cucumber, and radish for a crisp texture. The acidity of the dressing cuts through the density of the rice filling.

Serving with Crusty Sourdough Bread

Toasted sourdough or garlic bread is ideal for soaking up the remaining tomato sauce. Slice the bread thickly and brush with olive oil before toasting. This adds a crunchy element to the meal.

Adding Steamed Broccoli or Green Beans

Steamed green vegetables provide essential nutrients and a bright color to the plate. Broccoli or green beans can be steamed quickly in the same pressure cooker before preparing the peppers. Season them simply with salt and lemon juice.

Using Mashed Potatoes as a Base

For a more filling meal, serve the stuffed peppers on a bed of creamy mashed potatoes. The potatoes act as a sponge for the tomato sauce. This creates a cozy, hearty dinner option.

Storage and Meal Prep Advice

Refrigerating Cooked Peppers

Cooked stuffed peppers can be stored in an airtight container in the refrigerator for up to 3 days. Keep them submerged in some of the sauce to prevent the filling from drying out. Ensure the container is completely sealed to avoid odors.

Freezing Uncooked Stuffed Peppers

Freezing uncooked peppers preserves the texture better than freezing cooked ones. Place stuffed peppers on a tray to freeze individually, then move them to a freezer bag. Thaw them in the fridge overnight before pressure cooking.

Reheating Instructions for Best Texture

To reheat, place the peppers in a microwave-safe dish with a bit of extra sauce. Cover with a lid and heat in 1-minute intervals until hot. Alternatively, use an oven at 350°F (175°C) for 15 minutes for a firmer texture.

Prepping Filling in Advance

The meat and rice filling can be prepared 24 hours in advance. Store it in a covered bowl in the refrigerator. When you are ready to cook, simply stuff the raw peppers and proceed with the pressure cooker steps.

Common Questions and Troubleshooting

Can I use uncooked rice in the filling?

No, this recipe requires pre-cooked rice. Uncooked rice does not absorb enough liquid in the short 8-minute window, leaving the filling dry and the grains hard. Always use cooked rice for consistent results.

How do I stop the peppers from falling over?

To keep peppers upright, trim the bottom slightly so they have a flat base. You can also wedge them against each other closely on the trivet. This prevents them from tipping and spilling the filling.

What is the best way to remove the seeds?

Use a small paring knife to cut a circle around the top of the pepper. Reach inside with a spoon or your fingers to pull out the seed pod and membranes. This creates a clean cavity for the filling.

Why is my sauce too thin?

If the sauce is too thin, you can simmer it in the pot using the SAUTÉ function after the peppers are removed. Stir constantly for 3 to 5 minutes until the desired thickness is reached. Be careful not to over-reduce it into a paste.
