Hearty Crustless Quiche Bake with bacon, eggs, mushrooms, and a blend of sharp cheddar and Gruyère cheese. Perfect for breakfast, brunch, or a protein-packed meal, this easy quiche recipe is ready in under an hour and works well for make-ahead meal prep. Topped with green onions and chives, and served with sour cream or hot sauce, it’s a flavorful, low-carb alternative to traditional quiche.

Ingredients

For the Bake:

1 pound thick-sliced bacon
2 tablespoons butter
1 ½ cups chopped white button mushrooms
5 green onions, thinly sliced, divided
16 large eggs
1 teaspoon all-purpose seasoning (e.g., Lawry’s Seasoned Salt)
½ cup sour cream (light or regular), plus extra for serving
1 heaping cup shredded sharp cheddar cheese
1 heaping cup shredded Gruyère cheese
2 tablespoons chopped fresh chives (optional)
Hot sauce (optional, for serving)

Instructions

Roast the Bacon:
Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with foil. Arrange the bacon on the sheet and roast for 15 minutes, or until crisp. Transfer to paper towels to drain and cool.
Sauté the Vegetables:
Reduce the oven temperature to 350°F (175°C). In a 12-inch skillet, melt the butter over medium-low heat. Add the mushrooms and cook until softened, about 3–5 minutes. Stir in half of the green onions (reserve the rest for topping) and cook for another 1–2 minutes. Remove from heat and crumble the bacon into the skillet, stirring to combine.
Prepare the Egg Mixture:
Coat a 9 x 13-inch (3-quart) baking dish with nonstick cooking spray. For a taller bake, use a 2 ½ quart dish. In a large bowl, whisk the eggs lightly. Stir in the sour cream and all-purpose seasoning until blended. Small bits of sour cream are okay—they’ll bake in.
Assemble the Bake:
Pour the egg mixture into the prepared baking dish. Spoon the bacon and mushroom mixture evenly over the top. If making ahead, cover with plastic wrap and refrigerate overnight.
Bake:
Sprinkle both cheeses over the top. Bake uncovered for 25–30 minutes (add 5–10 minutes if chilled), until the center is set and the top is golden brown. Remove from oven and garnish with remaining green onions and chives. Let rest for 5 minutes before slicing.
Serve:
Serve warm with extra sour cream and hot sauce if desired.
