Keep reading—I’ll share all my ingredients, comfort hacks, and little tricks to make this mushroom-rich quiche a household star.

8 large eggs: The heart of our crustless mushroom quiche! Eggs give it that fluffy, rich base that’s both filling and comforting.

2 cups sliced mushrooms (white button or cremini): Mushrooms bring earthiness and umami, making this mushroom egg bake a family favorite.

1 cup shredded cheese (I love mozzarella or a sharp cheddar): Adds melty, gooey good vibes that kids and adults crave alike.

1/2 cup milk or cream: For dreamy softness. No cream? No worries, milk works just fine and lightens the dish.

1 small onion, diced: Sautéed onions add natural sweetness—a subtle but tasty comfort boost.

2 cloves garlic, minced: Garlic elevates the flavor without being overpowering; perfect for a low carb quiche that’s still comforting.

Salt and pepper to taste

Fresh herbs (optional, like thyme or parsley): For fresh flavor pops that brighten up this mushroom and cheese quiche.

Olive oil or butter for sautéing

You can find all these simple ingredients at your regular grocery store—nothing fancy, just solid comfort food staples. And here’s a little budget hack: if you don’t have fresh mushrooms, good quality canned mushrooms work too, just drain them well. Same goes for cheese—whatever you have on hand, cheddar, Monterey Jack, or even those shredded blends will make this crustless mushroom quiche comforting and delicious.

For busy families, chopping onions and mushrooms ahead of time or buying pre-sliced mushrooms saves precious moments. On hectic mornings, I often prepare the filling the night before so this crustless quiche recipe comes together in a flash.

My family feels that extra comfort when I toss in a handful of baby spinach or swap the cheese for a bold gruyere, inspired by the feel-good vibes from this mushroom gruyere pasta recipe. It’s all about making this crustless mushroom quiche your own cozy classic.

1. Preheat your oven to 375°F (190°C). This cozy temperature makes sure your crustless mushroom quiche sets perfectly without drying out.

2. Heat a skillet over medium heat and add a splash of olive oil or a knob of butter. Once hot, toss in your diced onions and garlic. Sauté until softened and fragrant—this base makes your quiche smell like home instantly.

3. Add the sliced mushrooms to the skillet. Cook them down until they’re tender and most of their moisture has cooked out. This step is key to preventing a soggy quiche later. Trust me, I learned that the hard way the first time.

4. In a mixing bowl, whisk the eggs with milk or cream, salt, and pepper. Whisk until the mixture is smooth and slightly frothy. This egg blend is what turns a simple mushroom egg bake into a fluffy, satisfying crustless quiche.

5. Stir your mushroom-onion mixture and any fresh herbs into the egg mixture. Then fold in the shredded cheese. The cheese adds that melty richness your family will adore.

6. Pour everything into a greased 9-inch pie dish or casserole pan. I like to grease with a little butter—it adds extra comfort and helps with clean-up.

7. Bake about 35-40 minutes. You’ll know your crustless mushroom quiche is ready when the edges are golden and the center is set but still slightly jiggly. If you poke it with a toothpick, it should come out mostly clean.

8. Let it cool for 5-10 minutes before slicing. This rest time helps the quiche finish setting up, making it easier to serve.

In my busy kitchen, this comforting crustless mushroom quiche usually takes under an hour from start to finish, including prep and bake time. While it’s in the oven, it’s prime time to clean up or prep lunches for the next day. When that mushroom and cheese quiche aroma fills the house, it’s hard not to get excited for family mealtime.

If your crustless mushroom quiche looks perfectly golden but still a bit wobbly—don’t fret. The residual heat finishes the job. I’ve learned patience pays off, even in the chaos of dinner prep! For shortcuts, chopped mushrooms from the produce aisle and pre-shredded cheese save a lot of time, keeping this a quick fix for weeknight comfort.
