Ingredients

Scale

Meat

  • 6 slices bacon

Vegetables

  • 2 cups mushrooms (sliced)
  • 1 cup onion (diced)
  • 1 pound green beans (trimmed)

Dairy

  • 2/3 cup half-and-half
  • 1/3 cup 2% milk
  • 1/4 cup full-fat cream cheese

Seasonings

  • 1 1/4 teaspoons sea salt
  • 1/4 teaspoon pepper

Instructions

  1. Preheat Oven and Heat Skillet: Preheat your oven to 350°F (175°C) and heat a large skillet over medium heat to prepare for cooking the bacon and vegetables.
  2. Cook Bacon: Place the bacon slices in the heated skillet and cook them until golden brown and crispy on each side, approximately 4 minutes per side. Once cooked, transfer bacon to a plate lined with paper towels to blot excess fat. Discard most of the bacon fat, leaving about 1 tablespoon in the skillet.
  3. Sauté Vegetables: Increase skillet heat to medium-high and add the sliced mushrooms and diced onions. Cook, stirring occasionally, until the vegetables become golden brown, roughly 3 minutes.
  4. Thicken Sauce: Stir in the half-and-half, 2% milk, cream cheese, sea salt, and pepper into the skillet with the vegetables. Bring the mixture to a boil while stirring constantly. Continue boiling and stirring until the sauce begins to thicken, about 4 minutes. Reduce heat to medium and cook, stirring occasionally, until very thick, about 7-8 minutes, achieving a consistency similar to condensed soup.
  5. Boil Green Beans: While the sauce thickens, bring a large pot of salted water to a boil. Add trimmed green beans and cook until just fork-tender, about 7-8 minutes. Drain the beans, then pat dry with paper towels to remove excess moisture.
  6. Assemble and Bake Casserole: Combine the cooked green beans with the thickened sauce in the skillet, stirring until beans are well coated. Transfer the mixture into an 8×8-inch baking pan and press evenly. Bake in the preheated oven for 15-20 minutes or until bubbly.
  7. Add Bacon Topping: While baking, pulse the cooked bacon in a food processor until it forms small crumbs. Remove the casserole from the oven, sprinkle bacon crumbs evenly on top, and bake for an additional 5 minutes.
  8. Serve: Remove casserole from the oven and serve immediately while warm and delicious.

Notes

  • Make sure to pat the green beans dry after boiling to prevent the casserole from becoming watery.
  • If you prefer a thicker bacon topping, crisp the bacon a bit longer before pulsing into crumbs.
  • For extra flavor, consider adding a teaspoon of garlic powder to the sauce.
  • You can substitute full-fat cream cheese with mascarpone for a milder flavor.
  • This dish can be prepared a day ahead; reheat covered in the oven before serving.
