These oven baked 4-ingredient beef stuffed mushrooms are the kind of simple appetizer that earns a permanent place in a family recipe box. They come together with very little prep, bake quickly, and deliver a savory combination of juicy mushrooms, browned beef, and crisp Parmesan that feels a bit more special than the short ingredient list suggests. Stuffed mushrooms have long been a popular party bite in American home cooking, and this pared-down version is especially useful when you want something warm, hearty, and easy to carry to a picnic, potluck, or holiday table.
Serve these mushrooms warm with other easy picnic and party foods such as pasta salad, deviled eggs, fresh cut vegetables, or a simple fruit tray. They also pair nicely with grilled burgers, barbecue chicken, or steak if you want to use them as a side instead of an appetizer. For drinks, iced tea, sparkling water, or a light red wine all work well with the earthy mushroom and beef flavors.
Oven Baked 4-Ingredient Beef Stuffed Mushrooms
Servings: 6
Ingredients
16 large cremini mushrooms, stems removed
1 pound ground beef
1 cup grated Parmesan cheese, divided
1/2 cup plain breadcrumbs
Directions
1. Preheat the oven to 400°F and line a baking sheet or shallow baking pan with foil. Gently wipe the mushrooms clean, remove the stems, and set the caps hollow-side up on the prepared pan.
2. In a skillet over medium heat, cook the ground beef until fully browned, breaking it up with a spoon as it cooks. Drain off any excess fat.
3. Stir the breadcrumbs and 1/2 cup of the Parmesan into the hot beef until evenly combined. Spoon the mixture into each mushroom cap, mounding it slightly.
4. Sprinkle the remaining 1/2 cup Parmesan over the tops of the stuffed mushrooms. Bake for 18 to 20 minutes, until the mushrooms are tender and the cheese is melted and golden brown. Serve warm.
Variations & Tips
Use white button mushrooms: If cremini mushrooms are not available, large white button mushrooms work well too. They are a little milder in flavor but still hold the filling nicely.
Make them ahead: You can brown the beef and stuff the mushrooms several hours in advance. Keep them covered in the refrigerator, then add the final Parmesan topping just before baking for the best texture.
Add the chopped stems: If you do not want to waste the mushroom stems, chop them finely and cook them along with the beef. That adds a little more mushroom flavor and keeps the filling extra moist.
Prevent soggy mushrooms: Avoid washing mushrooms under lots of running water, since they absorb moisture easily. A damp paper towel is usually enough to clean them, and baking them on a hot oven rack helps the excess moisture cook off quickly.
