Ingredients

Gathering the right ingredients is key to making these delicious stuffed baked onions. Quality fresh produce and good meat will make all the difference in the final taste.

Ingredient Notes

Large Yellow Onions: Choose firm, large onions that are relatively uniform in size for even cooking. Sweet onions like Vidalia also work wonderfully and will caramelize beautifully.
Ground Meat: Lean ground beef (80/20 or 85/15) is ideal as it provides flavor without too much grease. You could also use ground turkey, pork, or a mix.
Cheddar Cheese: Orange cheddar-style cheese adds a classic sharp and creamy element. Feel free to experiment with other cheeses like Monterey Jack, Gruyere, or a smoky provolone.
Bacon Bits: Pre-cooked bacon bits are convenient, but cooking and crumbling your own bacon will yield a fresher, crispier texture and richer flavor. Reserve some of the bacon fat for sautéing the meat if you go this route.
Seasonings: The basic salt and pepper are essential, but feel free to add garlic powder, onion powder, paprika, or a touch of dried herbs like thyme or oregano to enhance the flavor of the ground meat.

How to Make Stuffed Baked Onions

Follow these step-by-step instructions for perfectly tender and flavorful stuffed baked onions.

Helpful Cooking Tips

Pre-cook onions for tenderness: If you prefer very soft onions, you can par-boil them for 10-15 minutes after hollowing them out, then drain well before filling and baking. This also reduces baking time slightly.
Don’t discard the onion insides:Finely chop the removed onion centers and sauté them with your ground meat for extra flavor and to reduce waste.
Prevent sticking: A light spray of cooking oil on the aluminum foil or directly into the hollowed onions before filling can prevent any cheese from sticking.
Achieve crispy topping: For extra crispy bacon and a beautifully browned cheese crust, you can briefly broil the onions for the last 2-3 minutes of cooking, keeping a very close eye on them to prevent burning.
Even cooking: Arrange the onions in a single layer on your baking sheet to ensure they cook evenly.

Ingredient Substitutions

Ground Meat: Instead of ground beef, try ground pork, turkey, chicken, or a plant-based crumble for a vegetarian option.
Cheese: Any good melting cheese will work. Mozzarella, provolone, Monterey Jack, or a spicy pepper jack would be delicious alternatives to cheddar.
Bacon: If you’re not a fan of bacon, you can omit it or replace it with diced ham, crumbled sausage, or even toasted breadcrumbs for a textural crunch.
Vegetarian Option: For a meatless version, fill the onions with a mixture of sautéed mushrooms, bell peppers, rice, breadcrumbs, and cheese.

Variations

Mediterranean Stuffed Onions: Add feta cheese, chopped spinach, sun-dried tomatoes, and a pinch of oregano to the meat mixture.
Mexican Stuffed Onions:Incorporate taco seasoning into the ground meat, add a can of drained black beans, and top with Monterey Jack cheese and a dollop of salsa or sour cream after baking.
BBQ Stuffed Onions: Mix a tablespoon or two of your favorite BBQ sauce into the ground meat filling for a smoky, tangy twist.

Serving Suggestions

These stuffed baked onions are a meal in themselves, but they pair wonderfully with a simple side salad, roasted vegetables, or a warm crusty bread to soak up any delicious juices.

Storage and Reheating

Leftover stuffed baked onions can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, place them in an oven preheated to 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave them, but the topping may not be as crispy.

Frequently Asked Questions

Q: Can I prepare these ahead of time?
A: Yes, you can prepare the onions and the filling, stuff them, and store them uncooked in the refrigerator for up to 24 hours. Bake them as directed when ready to serve.

Q: What kind of onions are best for stuffing?
A: Large yellow onions, Spanish onions, or sweet onions like Vidalia are excellent choices due to their size and relatively mild flavor when cooked.

Q: How do I prevent the onions from falling apart?
A: Be gentle when hollowing them out. Leaving a few outer layers intact will help maintain their structure. Don’t over-stuff them.

Q: Can I freeze stuffed baked onions?
A: While possible, the texture of the onions can become a bit mushy after freezing and thawing. It’s best to enjoy them fresh, but if you must freeze, bake them first, then cool completely before freezing in an airtight container for up to 2 months. Reheat from frozen in the oven.

Ingredients

5 large yellow onions
1 lb (450g) ground beef (or other ground meat)
4 oz (115g) cheddar-style cheese, shredded or diced
4 slices bacon, cooked and crumbled (or 1/4 cup bacon bits)
1 tbsp olive oil
Salt and freshly ground black pepper to taste
Optional: 1/2 tsp garlic powder
Optional: 1/2 tsp onion powder

Instructions

Preheat your oven to 375°F (190°C). Prepare a baking sheet by lining it with aluminum foil for easy cleanup.
Prepare the onions: Carefully peel the onions. Cut off the top 1/4 inch and the very bottom root end, making a stable base. Using a small spoon or paring knife, carefully hollow out the center of each onion, leaving about 3-4 outer layers intact to form a sturdy cup. Finely chop the removed inner onion pieces and set aside.
Cook the filling: In a large skillet, heat the olive oil over medium heat. Add the ground beef and chopped inner onion pieces. Cook, breaking up the meat with a spoon, until the beef is browned and the onion is softened. Drain any excess grease.
Season the meat: Season the cooked ground meat mixture with salt, black pepper, garlic powder, and onion powder (if using). Stir well to combine.
Stuff the onions: Spoon the seasoned ground meat mixture evenly into each hollowed-out onion. Pack it gently but firmly.
Add cheese and bacon: Top each stuffed onion generously with the shredded or diced cheddar cheese and crumbled bacon bits.
Bake: Place the stuffed onions on the prepared baking sheet. Bake for 45-60 minutes, or until the onions are tender and slightly caramelized, and the cheese is melted and bubbly with some browned, crispy edges. If the cheese starts to brown too quickly, you can loosely tent the onions with foil.
Serve: Carefully remove from the oven. Let the onions rest for a few minutes before serving hot. Enjoy!
