Savory and satisfying, these Bacon and Cheddar Stuffed Mushrooms are quick to make and packed with protein and fiber. Perfect as an appetizer, snack, or side dish, they combine crispy bacon, tender mushrooms, and gooey Cheddar for a low-carb, nutrient-rich treat that’s ideal for everyday meals or entertaining.
Prepare the Bacon: Start by laying the bacon slices evenly in a large, deep skillet. Place the skillet over medium-high heat and cook the bacon slowly, turning occasionally, until it reaches a perfect golden-brown color and becomes crisp. Be patient—this ensures the bacon develops a rich, smoky flavor without burning. Once cooked, transfer the bacon to a paper towel-lined plate to drain excess grease. After cooling slightly, dice the bacon into small, bite-sized pieces and set aside for later use.
Preheat the Oven: While the bacon is cooking, preheat your oven to 400°F (200°C). Preheating ensures that your stuffed mushrooms cook evenly and the cheese melts perfectly. Set your oven rack in the middle position for the best results.
Clean and Prepare the Mushrooms: Gently clean each crimini mushroom using a damp paper towel or soft brush to remove any dirt. Avoid rinsing mushrooms under running water, as they can absorb moisture and become soggy. Carefully remove the stems from each mushroom cap and set the caps aside on a plate. Chop the stems finely—they will be cooked and incorporated into the flavorful filling.
Sauté Mushroom Stems and Onion: In a large saucepan, melt 1 tablespoon of butter over medium heat. Once melted, add the chopped mushroom stems along with the finely chopped onion. Stir the mixture constantly and cook slowly until the onion becomes translucent and tender, and the mushroom stems soften. This process enhances the natural flavors and creates a savory, aromatic filling base. Remove the saucepan from heat and allow the mixture to cool slightly.
Combine Filling Ingredients: In a medium mixing bowl, combine the sautéed mushroom stem and onion mixture with the diced bacon. Add ½ cup of shredded Cheddar cheese and mix thoroughly. Ensure each ingredient is evenly distributed to create a flavorful, cohesive filling. This mixture should be moist, savory, and aromatic, ready to fill the mushroom caps.
Stuff the Mushroom Caps: Carefully spoon the prepared filling into each mushroom cap, pressing lightly so that the mixture stays in place but doesn’t overflow. Fill each cap generously for a satisfying bite, ensuring each mushroom holds a good portion of the bacon and cheese mixture.
Bake the Mushrooms: Place the stuffed mushrooms on a baking sheet or in a shallow baking dish. Transfer them to the preheated oven and bake for 15 minutes. During this time, the cheese inside the filling will melt, the mushrooms will soften slightly, and the flavors will meld together beautifully. Keep an eye on them to prevent over-baking.
Add Topping Cheese: After the initial baking, remove the mushrooms from the oven and sprinkle the remaining ¼ cup of Cheddar cheese evenly over the tops of the stuffed mushrooms. Return them to the oven for an additional 2–3 minutes, or until the cheese is fully melted, slightly golden, and bubbly. This final touch adds an irresistible cheesy topping.
Serve and Enjoy: Once baked to perfection, carefully remove the mushrooms from the oven. Allow them to cool for a few minutes, making them easier to handle and enhancing the flavors. Arrange the mushrooms on a serving platter and serve warm. These savory, protein-rich bites make a perfect appetizer, side dish, or snack for any occasion.
Optional Garnish and Tips: For an extra touch, you can garnish the stuffed mushrooms with finely chopped fresh parsley or a light sprinkle of paprika. This adds color and enhances visual appeal. These mushrooms pair wonderfully with a crisp salad or a light soup, making them versatile for everyday meals or entertaining guests.
Notes
Always choose fresh, firm mushrooms for the best texture; avoid those with soft spots or wrinkles.
Crisp bacon adds flavor and texture; cook it just until golden-brown for the ideal balance of crunch and savory taste.
The filling can be made ahead of time and stored in the refrigerator for up to 24 hours, which makes this recipe excellent for meal prep or entertaining.
Use a sharp Cheddar for a more pronounced flavor, or a mild Cheddar for a subtle, creamy taste.
Avoid overstuffing the mushroom caps, as this can cause the filling to spill during baking.
