How Long to Bake Stuffed Peppers at 400 F

Jump to Recipe

Stuffed peppers are an excellent way to create a complete meal in a single dish. They're the perfect blend of fresh, flavorful, and filling, and they’re a great appetizer or the main course, depending on your preference. However, depending on what you use to stuff the peppers, you may have to bake them longer than you think.

If you’re using a pre-made filling, such as rice or quinoa, you’ll only have to bake the peppers for about 20 minutes. If you’re using raw meat or vegetable, though, the peppers will need to be baked for about 30 minutes. And if you’re using a combination of raw and cooked ingredients, bake the peppers for about 25 minutes at 400° Fahrenheit.

No matter if you’re vegan, vegetarian, or eat most foods, it always helps to check a recipe or two before you start cooking. This guide will hopefully help you determine how long to bake your stuffed peppers so they turn out perfect every time.

Regardless of the Filling, Always Roast Peppers at 400° Fahrenheit

Although you'll set your oven to bake, you're essentially roasting the peppers by cooking them at 400° Fahrenheit. This high temperature helps to break down the peppers' cell walls, making them softer, sweeter, and more flavorful. If you were to attempt this at a lower temperature, the peppers would take significantly longer to cook and wouldn't taste as nice.

A Precooked Filling Will Take Less Time to Bake

If you're vegan or vegetarian, you may prefer to use a filling made from rice, quinoa, barley, spices, and other vegetables. This makes for a delicious, healthy, and filling meal, but it won't take as long to bake as a stuffed pepper that contains raw meat or vegetables. Since the grains and vegetables are already cooked, you'll only need to roast the peppers for about 20 minutes.

A Combination of Raw and Cooked Filling Will Take a Bit Longer to Bake

If you want to add meat to your filling, you'll have to adjust the baking time. Eating raw ground meat is incredibly risky and can lead to food poisoning, so it's important to cook it thoroughly. However, you don't want the meat to be tough or dry. The best way to ensure that the meat is cooked through is to use a combination of raw and cooked ground meat.

For example, if you're using ½ pound of ground beef, use ¼ pound of cooked ground beef and ¼ pound of raw ground beef. This way, the raw beef will cook through without coming out dry, flavorless, and tough. Bake the peppers for about 25 minutes at 400° Fahrenheit.

If You're Using All Raw Filling, Bake the Peppers for Even Longer

As we mentioned before, eating raw ground meat is incredibly risky. If you must use all raw ground meat in your filling, be sure to cook the peppers for at least 30 minutes at 400° Fahrenheit. This will help to ensure that the meat is cooked through and safe to eat.

Baking Times May Vary Depending on the Size of the Pepper

The baking times we've given are general guidelines, and your peppers may take longer or shorter to bake, depending on their size. For example, if you're using small peppers, they'll cook more quickly than large peppers. Additionally, if you stuff the peppers very full, they'll take longer to cook than peppers that are only lightly stuffed.

As a general rule of thumb, check the peppers after 20 minutes of baking. If they're not quite done, bake them for an additional 5-10 minutes. Continue checking the peppers every 5 minutes or so until they're cooked to your liking.

Line the Baking Sheet with Aluminum but Don’t Cover the Peppers

You might be tempted to put the peppers in a casserole dish and cover them with foil while they bake. However, this isn't necessary, and it can actually make the peppers soggy. Instead, line the baking sheet with aluminum foil or parchment paper.

This will help to prevent the peppers from sticking, and it will make cleanup a breeze. Don't worry about covering the peppers while they bake. The foil or parchment paper will help to keep the peppers from drying out, and the steam that escapes from the peppers will help to keep them moist.

Cut the Peppers Vertically to Cook them Faster

Although most stuffed pepper recipes recommend cutting the top off of the peppers and then adding the filling, we recommend doing things a bit differently if you're in a rush. First, cut the peppers in half vertically. Then, remove the seeds and ribs. Finally, add the filling and bake the peppers as directed.

Cutting the peppers vertically will increase the amount of surface area that's exposed to the heat, which will help the peppers to cook more quickly. Additionally, removing the seeds and ribs will help the peppers to cook even faster and eliminate any unwanted bitterness.

Add Cheese at the End

If you're planning to top the peppers with cheese, we recommend waiting until the peppers are almost done cooking. Then, add the cheese to the tops of the peppers and bake for an additional 5-10 minutes or until the cheese is melted and bubbly. If you try adding the cheese from the start, there's a good chance that it will burn before the peppers are cooked through.

Prep the Peppers Ahead of Time, Freeze Them and Bake Them When You’re Ready to Eat

If you're short on time, you can always prepare the peppers ahead of time and then freeze them. To do this, cut the peppers in half, remove the seeds and ribs, and then add the filling. Place the peppers on a baking sheet, and then freeze them for 2-3 hours, or until they're solid.

Once the peppers are frozen, transfer them to a freezer-safe bag or container. When you're ready to eat, thaw the peppers overnight in the fridge. Then, bake them as directed.

A Few Top Tips to Help You Make Unforgettable Stuffed Peppers

As far as we’re concerned, all stuffed peppers are good stuffed peppers but you can upgrade your results by applying some of these top cooking tips. They’re not entirely necessary but they can help to add a little more oomph to your meal.

Experiment with Different Types of Peppers

Although most stuffed pepper recipes recommend using a standard bell pepper, don’t be afraid to experiment with different varieties. In Puebla, Mexico, it’s quite popular to stuff poblano peppers with a variety of fillings, including meat, cheese, and vegetables. As long as the peppers are large enough to cut open and stuff, you can make a delicious and healthy meal.

Experiment with Different Types of Meat

Likewise, don't feel restricted to using ground beef. If you have ground chicken, turkey, lamb, or pork on hand, feel free to use it instead. You can even use a mixture of meats to combat dryness and increase the flavor. Just be sure to cook the meat thoroughly before adding it to the peppers.

Use a Mixture of Cheeses

If you're planning to top the peppers with cheese, we recommend using a mixture of cheeses for the best flavor and texture. For example, you might use a combination of cheddar, mozzarella, and Parmesan. You could also use a single cheese, such as Gruyere or Swiss.

Grill the Peppers

First If you're short on time, you can always roast the peppers in the oven. However, if you have a bit more time, we recommend grilling the peppers first. This will help to char the skin, which will add a smoky flavor to the peppers. Just be sure to remove the peppers from the grill before they're completely cooked through.

Add a Kick of Heat

If you want to add a bit of heat to your meal, don't be afraid to add a few extra jalapenos to the mix. You could also use a hotter variety of pepper, such as a serrano or habanero. Just be sure to remove the seeds and ribs before adding the peppers to the dish.
