Ah, the lessons learned!

What makes this mushroom quiche without crust special is how adaptable it is. Some mornings, I toss in fresh spinach or swap out the usual cheddar for creamy feta.

Alright, girl, when it comes to making the perfect crustless mushroom quiche, having the right ingredients on hand really sets you up for success. I always say the secret starts with fresh mushrooms—preferably cremini or white button mushrooms—that give the quiche that lovely earthy undertone. Here’s exactly what I use for my crustless mushroom quiche:

• 8 ounces fresh mushrooms, sliced (I usually grab cremini—they’re full of flavor but budget-friendly)
• 6 large eggs, because nothing sets a quiche better than them
• 1 cup shredded cheese (I love sharp cheddar or a mix of mozzarella and Parmesan for a cheesy crustless quiche feel)
• 1/2 cup half-and-half or whole milk to keep it creamy but not runny
• 1/2 cup chopped onions (sometimes I swap these for shallots for a milder touch)
• 2 cloves garlic, minced, for that subtle flavor punch
• Salt and freshly cracked pepper, to taste
• 1 tablespoon olive oil or butter for sautéing the mushrooms and onions
• Optional: fresh herbs, like thyme or parsley, chopped for freshness

When I’m shopping for these ingredients, I always look for mushrooms that are firm and clean—no damp spots. You can find great deals at your local farmers’ market or the grocery store’s organic section. And here’s a little crustless mushroom quiche trick I learned: slice your mushrooms and onions ahead of time, toss them in a zip bag, and store them in the fridge. It makes assembly a breeze during busy weekday mornings.

If you’re trying to keep costs down, frozen mushrooms work surprisingly well when fresh aren’t available—just make sure to thaw and drain them thoroughly to avoid watery quiche. Also, using whatever cheese you have on hand keeps things flexible. For leftover storage, I keep the eggs and milk well chilled and plan to use them within a few days, but mushrooms are best fresh or frozen.

Okay, here’s the fun part—rolling up your sleeves for this easy mushroom quiche recipe. Don’t worry if your crustless mushroom quiche looks a little rough at first; mine definitely didn’t start perfect! Follow along with me, and I’ll share what I’ve picked up over many batches. In my kitchen, this crustless mushroom quiche usually takes about 45 minutes from start to finish, including prep and bake time.

1. Preheat your oven to 375°F (190°C). Grease a 9-inch pie dish or quiche pan with butter or non-stick spray.
2. Sauté the mushrooms and onions. Heat your olive oil or butter in a skillet over medium heat. Toss in your sliced mushrooms and chopped onions. Cook until the mushrooms release their moisture and start to brown, about 7-10 minutes. Add the minced garlic in the last minute to avoid bitterness.
3. Whisk the eggs and milk. In a large mixing bowl, beat together the eggs and half-and-half. I like to add my salt and pepper here too so it’s evenly seasoned.
4. Combine everything. Stir in the sautéed mushroom mixture and shredded cheese (save a little cheese for sprinkling over the top if you want a cheesier crustless quiche finish). You can also mix in fresh herbs at this point if you’re feeling fancy.
5. Pour into prepared pie dish. Spread the mixture evenly, smooth the top, and sprinkle the reserved cheese over it.
6. Bake the crustless mushroom quiche. Pop it in the oven for about 30-35 minutes. You’ll know it’s done when the center is set but still slightly jiggly (it will firm up as it cools), and the top is golden.
7. Cool and serve. Let it sit for at least 10 minutes before slicing—it makes the best cheesy crustless quiche texture!

While it’s baking, I usually tidy up the kitchen or set the table, grab a cup of coffee, and breathe in that wonderful mushroom and cheese aroma filling the air. It never fails to make my mouth water! One tip from personal experience—don’t rush slicing the quiche right out of the oven; otherwise, it tends to fall apart, and we’ve all been there with a crumbled crustless mushroom quiche.

We often whip up this mushroom quiche without crust for weekend brunch, but it’s also a winner for easy weeknight dinners.

Presentation-wise, I like to sprinkle fresh herbs over the top just before serving to bring a pop of color and a burst of fresh flavor.

Friends have often told me this is their favorite crustless mushroom quiche recipe because it’s easy but tastes like I spent hours on it. Honestly, that’s the best compliment a busy home cook can get!

Q: Can I make my crustless mushroom quiche ahead of time?
A: Absolutely! I often prepare mine the night before and bake it in the morning. If you want to pre-bake it fully, cool it completely and store in the fridge, then reheat gently in the oven. You know what I do when my crustless mushroom quiche is prepped? I wrap it tightly with foil to keep it moist.

Q: How do I keep my crustless mushroom quiche from getting watery?
A: Great question! Mushrooms release quite a bit of moisture. To avoid sogginess, I learned the hard way to sauté mushrooms until most of their liquid evaporates before adding them to the egg mixture. Also, draining any excess liquid before mixing helps keep your crustless mushroom quiche firm and flavorful.

Q: Can I substitute dairy to make this a dairy-free crustless mushroom quiche?
A: Yes, you can definitely swap half-and-half with unsweetened almond milk or coconut milk, and use a dairy-free shredded cheese alternative. The texture changes a bit but still very tasty.

Q: My crustless mushroom quiche cracks on top after baking; what’s wrong?
A: That usually means it’s overcooked or baked at too high a temperature. I recommend keeping oven temp steady at 375°F and checking the quiche a few minutes before the timer ends. Remember, a slight jiggle in the center means it’s perfectly done.

Q: Can I add other veggies to the crustless mushroom quiche?
A: Totally. Spinach, bell peppers, zucchini, or even kale work beautifully. Just sauté them well to remove excess moisture like I do with mushrooms.

Q: What cheese works best in crustless mushroom quiche?
A: Sharp cheddar is my go-to for flavor and meltiness, but a combo of Monterey Jack, mozzarella, or grated Parmesan brings a lovely cheesy crustless quiche texture. For a jazzed-up flavor, feta or goat cheese add tanginess.

Q: How should I store leftover crustless mushroom quiche?
A: Cover it tightly and keep refrigerated for up to 3 days. Reheat slices gently in the microwave or oven. Leftover crustless mushroom quiche also freezes well if wrapped well—it’s a lifesaver for busy weeks.
