Make magic in your kitchen with this impossible quiche! It’s basically a self-crusting quiche that’s loaded with eggs, bacon, cheese, and onions and finished off with a fluffy Bisquick outer layer. It’s creamy, cheesy, and impossibly tasty – the perfect all-in-one breakfast or brunch meal. It takes 5 minutes to put in the oven and you’ll have a delicious, hearty meal ready to enjoy.
Let me tell you about a simple recipe that’s impossible not to love – the Bisquick Quiche, or as many call it, the Impossible Quiche. Many years ago, we visited one of Mom’s friends and she served us this delicious savory pie that I couldn’t get enough of. When I asked her about it, she pulled out an old recipe card from her kitchen drawer and told me it came from a Bisquick box from way back in the 70s. I was intrigued. No crust? Just mix and bake? Could it really be that simple? It turns out, yes – it could be!
Impossible quiche is named so because it forms its own crust while baking, making it seem “impossible” that a simple recipe could make a fully formed quiche without needing to make a traditional crust. The magic happens when you mix all the ingredients together, and during baking, the flour or Bisquick settles at the bottom, creating a thin, crust-like layer. If that’s not amazing, then I don’t know what is!
This has been a family favorite since. It’s perfect for brunches, family gatherings, or lazy weekend breakfasts. It’s always a hit at potlucks, too. This recipe has truly stood the test of time, deliciously nostalgic but endlessly adaptable to modern tastes.

Ingredients You Need
- Bacon: I use crumbled bacon for a nice textural contrast. Use turkey bacon if you want a lighter option.
- Swiss cheese: Melts into the quiche, making it rich and creamy. I recommend shredding the cheese yourself, as it melts better than the pre-shredded kind.
- Yellow onion
- Eggs: The foundation of any quiche. Eggs give the dish its structure while keeping it light and fluffy.
- Milk: For a smoother, creamier consistency. I use whole milk, but feel free to use your favorite.
- Salt
- Ground black pepper
- Bisquick: The secret ingredient! It forms a light crust as the quiche bakes, making this recipe truly “impossible” to resist.
Step-By-Step Instructions
Impossible quiche is the perfect way to start your day – no crazy ingredients, almost effortless, and it looks so appetizing! Ready to make some kitchen magic? Just follow the 3 simple steps below:
Step 1: Prep
Preheat the oven to 400F. Lightly grease a 10-inch pie plate.
First, sprinkle your cooked bacon in an even layer across the bottom of the dish. Top it with cheese then a layer of onion. Follow this exact order.
Step 2: Make the batter
Next, beat the eggs in a medium mixing bowl. Add milk, salt, and pepper. Mix in the Bisquick until smooth. Pour the mixture over the pie plate over the other ingredients.
Step 3: Bake
Bake for 35 minutes until a toothpick inserted in the center comes out clean and the top is nicely golden brown. Cool on a wire rack for 15 minutes before cutting and serving warm. Enjoy!
Substitutions
Bisquick quiche only calls for simple, everyday ingredients that you may already have in your kitchen. In case you’ve run out of some or want to switch up the ingredients, here are my recommended substitutions:
- Bacon: Swap out bacon for chopped ham, sausage slices, Spam cubes, or a plant-based meat alternative like veggie bacon for a vegetarian option.
- Swiss cheese: If you don’t have Swiss cheese, use cheddar, Gruyère, mozzarella instead.
- Yellow onion: Although they may offer slightly different flavor profiles, you can substitute yellow onion with red or green onion, or shallots. You can also use leeks for a milder taste.
- Milk: Substitute with almond milk, oat milk, or any other non-dairy milk alternative if you’re aiming for a dairy-free version. For a richer quiche, try using cream or half-and-half.
Variations
The beauty of the impossible quiche is how easily you can switch things up to fit different tastes or tweak it according to what you have on hand. While this classic Bisquick quiche is already delicious, make it your own by adding your favorite mixins. If you need ideas, here are some of my favorite variations:
- Who can say no to caramelized onions? Take it up a notch by caramelizing the onions first. They’ll be richer and sweeter, and taste amazing with the bacon and Swiss cheese.
- Swap out the bacon for cooked diced ham and switch to sharp cheddar cheese for a classic ham and cheese pairing. If you want a vegetarian version of this, replace the meat with some cooked broccoli florets.
- Make an all-veggie filling by replacing the bacon with sautéed spinach and mushrooms, and chopped red or yellow bell peppers.
- Replace bacon with spicy sausage or chorizo for a smoky, flavorful kick.
- Add chopped jalapeños (with seeds for extra heat, or remove them for a milder version) or a sprinkle of red pepper flakes to the Bisquick mixture for added spice.
Expert Tips
- Avoid a soggy quiche: If using watery vegetables like zucchini, tomatoes, and mushrooms, drain them properly beforehand or sauté them first to remove excess moisture.
- Pre-cook add-ins: Whether you’re using bacon, sausage, or vegetables, make sure to pre-cook them to remove excess moisture and ensure a crisp texture.
- Use your leftovers: If you have any leftovers like roasted vegetables and cooked meats, use them to make this dish to avoid food waste.
- Be careful not to overbake: Always check for doneness – the quiche is done when it’s ‘just’ set in the middle and a toothpick inserted into the center comes out clean. Overcooking will result in a dry quiche.
- Let it set: Allow the quiche to cool and rest for at least 15 minutes before slicing. This will help it set and make cutting easier.
How to Store This Recipe
Place leftovers in an airtight container and store in the refrigerator for up to 4 days, or in the freezer for up to 1 month. To reheat, warm in the oven, covered in foil, at 350 F for 20 minutes, or until warmed through. A frozen quiche can be warmed straight out of the freezer, but will take longer to reheat, about 30 minutes.
What to Serve with Impossible Quiche
Impossible quiche is best enjoyed with some toast and warm coffee for an easy, comforting breakfast. Serve it with a fresh salad, avocado slices, or a side of fresh fruit for a light meal, or pair it with some roasted seasonal vegetables, parmesan potatoes, a light pasta, or slices of crusty bread for a more filling one.
