Another reason for their popularity is the time they save. Whether you’re cooking for one or feeding a family, you can have dinner on the table with minimal effort. Many people love that they can heat the peppers in the oven or microwave without sacrificing flavor. For busy weeknights, that flexibility is a huge plus.

Of course, their wide appeal also comes from their taste. The filling is savory and satisfying, with melted cheese on top that creates a comforting, home-cooked feel—even if it came from the fridge section. Because of that, many families now keep these peppers stocked as a reliable, go-to meal.

Step-by-step process of cooking Costco stuffed peppers at home — How to make homemade stuffed peppers like Costco’s — from pan to plate

How to Make Costco Stuffed Peppers at Home

Recreating the comforting taste of Costco stuffed peppers at home is easier than it seems. With a few everyday ingredients and basic prep, you can make a filling, flavorful dish that’s perfect for busy weeknights or relaxed weekends.

Step 1: Prep the Oven and Peppers

Start by setting your oven to 375°F so it has time to heat up. Lightly grease a baking dish, preferably a 9×13-inch size, and keep it nearby.

Decide how you’d like to present the peppers. If you want full-sized servings, go with six whole bell peppers. Cut off the tops, remove the seeds, and clean out the white inner ribs. For smaller portions, slice three peppers lengthwise and clean both halves.

Don’t waste the pepper tops. Dice the trimmed pieces (excluding stems) and set them aside—they’ll add extra flavor to your filling.

Step 2: Sauté the Base

Warm a bit of olive oil in a wide pan set over medium heat. Once the oil is warm, toss in your diced onions and chopped pepper tops. Cook for a few minutes, stirring occasionally, until the vegetables begin to soften.

Add your preferred ground meat—either beef or turkey—and cook until fully browned. Use a spoon to break it apart as it cooks for an even texture.

Step 3: Build the Filling

Stir in about 14 ounces of tomato-based sauce. Stir in the dry rice along with your chosen liquid—either water or broth—and a pinch of salt. Reduce the heat, cover, and cook slowly for 15 to 18 minutes until the rice is tender and the mixture thickens. The mixture should thicken and the rice should be tender.

Once the filling is ready, mix in one cup of shredded Parmesan cheese. Give it a quick taste and sprinkle in extra salt or pepper if the flavor needs a boost.

Step 4: Fill and Bake

Spoon the filling into your prepared peppers and arrange them upright in your baking dish. If you prefer a saucier result, drizzle the remaining tomato sauce over the tops.

Cover the dish tightly with foil and bake for about 40 minutes. When the peppers are soft, remove the foil and sprinkle on the rest of the cheese. Return the dish to the oven for a few more minutes, just long enough for the cheese to melt and bubble.

Step 5: Serve with a Fresh Finish

Allow the stuffed peppers to rest briefly so the filling can settle before serving them warm. For a bright final touch, sprinkle fresh parsley on top. These homemade stuffed peppers offer rich flavor, cheesy comfort, and a homemade touch that takes them beyond the store-bought version.

Best Cooking Methods: Oven vs. Air Fryer

When it comes to heating Costco stuffed peppers, both the oven and air fryer offer solid results—but each method has its strengths. Your choice depends on how much time you have and what texture you prefer.

Oven: Classic and Consistent

The oven remains the most reliable method, especially when cooking multiple peppers. Baking at 375°F allows the filling to heat evenly while the cheese melts perfectly across the top. Covered baking keeps the peppers moist, and finishing them uncovered adds a golden, bubbly layer. This method takes about 45 minutes total, but the result is warm, tender peppers with a familiar homemade feel.

Air Fryer: Quick and Crisp

If you’re short on time or reheating a smaller batch, the air fryer is a fantastic option. It produces a slightly crispier exterior and takes less time overall. To air fry, preheat your machine to 350°F. Place the stuffed peppers inside and cook for 12–15 minutes, checking for doneness around the 10-minute mark. This method is especially handy when you want dinner fast without compromising flavor.

So, how long to cook Costco stuffed peppers in an air fryer?
Set the temperature to 350°F and heat them for 12–15 minutes. If the cheese starts to brown and bubble, they’re ready to serve.

What to Serve with Costco Stuffed Peppers

Although Costco stuffed peppers can stand alone as a full meal, pairing them with the right sides can elevate your dinner. Since the peppers already contain meat, rice, and sauce, aim for sides that add freshness, crunch, or a contrast in flavor.

A crisp green salad is always a smart option. Toss together mixed greens with a light vinaigrette to balance the richness of the filling. Roasted vegetables like zucchini, carrots, or asparagus also work well, especially if you’re already using the oven.

For something heartier, serve them alongside garlic bread or a piece of crusty sourdough. Bread on the side is perfect for soaking up any sauce left behind on the plate. If you prefer a lighter touch, try lemony couscous or steamed green beans with a dash of sea salt.

FAQs About Costco Stuffed Peppers

How do you cook stuffed peppers from Costco?

Place them in a preheated 375°F oven and cook for about 40 to 45 minutes until heated through. Keep the peppers covered with foil during most of the baking time to lock in moisture, then uncover them for the last 5 to 10 minutes so the cheese can melt and lightly brown. If using a microwave, heat one pepper for 5–7 minutes on high, checking the center for warmth.

They pair well with salads, roasted vegetables, or garlic bread. You can also serve them with couscous or steamed greens for a lighter side. Each adds variety without overpowering the flavors.

Are Costco stuffed bell peppers good for you?

Yes, they can be a balanced meal depending on your dietary needs. They contain protein, vegetables, and carbs, and come in at around 320–350 calories per pepper. Watch the sodium and cheese content if you’re monitoring your intake.

Final Tips & Storage Advice

If you plan to make Costco stuffed peppers ahead of time or want to save leftovers, proper storage and reheating make all the difference.

Refrigerating Leftovers
Allow the peppers to cool fully, then store them in a sealed container. They can be refrigerated for up to four days without losing flavor. For best results, reheat them in the oven at 350°F for 15–20 minutes or microwave individually for 3–5 minutes, depending on size.

Freezing for Later
Stuffed peppers freeze surprisingly well. Individually cover each cooked pepper using foil or plastic wrap, then transfer them into a freezer-friendly storage bag or container. Label with the date and store them for up to 2 months. To reheat from frozen, bake at 375°F for about 45–50 minutes, or until heated through.

Helpful Tips for Success

If using halved peppers, place them close together in the dish so they hold their shape while baking.
For added flavor, try mixing shredded mozzarella with Parmesan before topping.
Use a slotted spoon to avoid watery filling when transferring cooked peppers to plates.

Whether you’re prepping ahead or enjoying them fresh from the oven, these homemade stuffed peppers offer both convenience and comfort. And with just a little planning, they’ll taste just as good the next day—or even weeks later.
