Oven Baked 4-Ingredient Beef Stuffed Mushrooms
Servings: 6
Ingredients
16 large cremini mushrooms, stems removed
1 pound ground beef
1 cup shredded provolone cheese
1 tablespoon ranch seasoning mix
Directions
1. Preheat your oven to 375°F and line a baking sheet or shallow baking pan with foil. Gently wipe the mushrooms clean, remove the stems, and set the caps open-side up on the prepared pan.
2. In a skillet over medium heat, cook the ground beef until browned and fully cooked, breaking it into small crumbles as it cooks. Drain off any excess grease, then stir in the ranch seasoning mix.
3. Spoon the cooked beef mixture into each mushroom cap, filling them generously. Top each one with a little shredded provolone cheese.
4. Bake for 15 to 18 minutes, or until the mushrooms are tender and the cheese is melted and bubbly. Serve warm.
Variations & Tips
For extra flavor: If you have a little more than four ingredients on hand, a spoonful of finely chopped onion or a sprinkle of garlic powder added to the beef can make these even more savory.
For picky eaters: Use a mild shredded mozzarella or Monterey Jack in place of provolone if your family prefers a softer, more familiar cheese flavor.
To keep them from getting watery: Mushrooms naturally release moisture as they bake, so avoid rinsing them under lots of water. A quick wipe with a damp paper towel works best.
Make-ahead tip: You can brown the beef and clean the mushrooms ahead of time, then stuff and bake them just before guests arrive so they come out hot and melty.
Size tip: Try to choose mushrooms that are close in size so they bake evenly and look nice on the serving tray.
