Roasted mushrooms stuffed with cheesy loaded mashed potatoes is the appetizer mashup you didn’t know you needed. Use same-size mushrooms so they cook evenly. If you don’t have leftover mashed potatoes, opt for store-bought.

Ingredients

  • 4 slices bacon, chopped

  • 32 large cremini mushrooms, stemmed (about 1 1/2 lb.)

  • 1 1/2 cups shredded sharp Cheddar cheese, divided

  • 1 cup leftover mashed potatoes

  • 2 tablespoons sour cream plus 1/4 cup, divided

  • 1/4 cup thinly sliced scallions, plus more for garnish

  • 1/8 teaspoon salt

Directions

  1. Preheat oven to 375°F. Line a large rimmed baking sheet with parchment paper. Cook bacon in a large nonstick skillet over medium heat, stirring often, until crisp, about 5 minutes. Transfer to a paper-towel-lined plate.

  2. Carefully carve out any remaining mushroom stems with a spoon or paring knife to leave a clean cavity. Place mushrooms, stem-sides down, on the prepared baking sheet. Bake until they have released most of their moisture, about 20 minutes.

  3. Meanwhile, stir 1 cup Cheddar, mashed potatoes, 2 tablespoons sour cream, scallions, salt and 1/4 cup of the cooked bacon together in a medium bowl.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
