Description

This Crustless Quiche Bake is a savory, hearty dish packed with crispy bacon, sautéed mushrooms, green onions, sharp cheddar, and Gruyère cheese. It’s perfect for breakfast, brunch, or a light dinner, and being crustless, it’s lower in carbs and easier to prepare than traditional quiche. The dish is baked until golden and fluffy, then topped with fresh herbs and served with sour cream and optional hot sauce for an extra kick.

Ingredients

Meat and Dairy

  • 1 pound thick-sliced bacon
  • 2 tablespoons butter
  • 16 large eggs
  • ½ cup sour cream (light or regular, plus additional for serving)
  • 1 heaping cup shredded sharp cheddar cheese
  • 1 heaping cup shredded Gruyère cheese

Vegetables and Herbs

  • 1 ½ cups chopped white button mushrooms
  • 5 green onions (thinly sliced, divided)
  • 2 tablespoons chopped fresh chives (optional)

Seasonings

  • 1 teaspoon all-purpose seasoning (like Lawry’s Seasoned Salt)

Optional

  • Hot sauce (for serving)

Instructions

  1. Preheat and roast bacon: Preheat your oven to 400°F. Line a rimmed baking sheet with foil and place the thick-sliced bacon in a single layer. Roast in the oven for 15 minutes or until the bacon is nicely crisped. Remove from the oven and transfer the bacon to paper towels to drain excess grease.
  2. Reduce oven temperature: Lower the oven temperature to 350°F in preparation for baking the quiche mixture.
  3. Sauté mushrooms and green onions: In a 12-inch skillet, melt the butter over medium-low heat. Add the chopped mushrooms and cook for several minutes until they soften. Add about half of the sliced green onions and sauté for another 1-2 minutes. Remove from heat.
  4. Combine bacon and vegetables: Crumble the roasted bacon into the skillet with the sautéed mushrooms and green onions. Stir gently to combine all ingredients evenly.
  5. Prepare the baking dish: Lightly coat a 9 x 13-inch (3-quart) baking dish with nonstick cooking spray. If a thicker casserole is desired, use a 2½-quart dish instead.
  6. Mix eggs and seasonings: In a large bowl, lightly whisk the eggs. Add the sour cream and all-purpose seasoning, whisking again until blended. Small bits of sour cream may remain, which is fine.
  7. Assemble quiche bake: Pour the egg mixture into the prepared baking dish. Evenly spoon the bacon and mushroom mixture over the top. At this stage, if you want to serve later, cover with plastic wrap and refrigerate overnight.
  8. Add cheese and bake: When ready to bake, sprinkle the shredded cheddar and Gruyère cheeses evenly over the top. Bake uncovered for 25-30 minutes, or 30-40 minutes if chilled, until the center is set and the top is golden brown.
  9. Finish and serve: Remove the quiche bake from the oven and sprinkle with the remaining green onions and chopped fresh chives if using. Let it rest for 5 minutes before slicing. Serve warm with additional sour cream and optional hot sauce.

Notes

  • If you prefer a higher, thicker casserole, use a 2½-quart baking dish instead of a 3-quart dish.
  • The recipe can be assembled a day ahead and stored in the refrigerator, baking time will be slightly longer if chilled.
  • To make it easier to slice, allow the quiche to rest briefly after baking.
  • Use sharp cheddar and Gruyère for a rich, flavorful cheese blend that melts well.
