Here’s the best recipe for Bisquick Impossible Quiche! This classic recipe makes a delicious veggie quiche with a buttery biscuit crust and is made using only one mixing bowl.

You’ll be amazed at how this impossible quiche bakes up into two distinct layers, and you’ll never need to roll out any pie crust dough.

At some point, the Bisquick Impossible Quiche recipe must have been published on the back of a Bisquick box, because this is one of those “vintage” recipes that everybody’s mom and grandma knows how to make!

This isn’t the same as a classic quiche pastry, but it’s just as delicious, with a magic crust layer on the bottom and a rich egg custard on top. My version of this Bisquick Quiche recipe is vegetarian and deliciously filled with broccoli and cheddar cheese.

Feel free to vary the add-ins though! Turn this into a Bisquick quiche Lorraine with ham and Swiss, or try it with bacon or sausage mixed in for a hearty breakfast bake.

For more perfect quiche mix-in ideas, check out my recipe for Mini Quiche! I have a whole list there.

Easy Impossible Quiche

  • Quick and Simple Preparation – It’s called a Magic Quiche or Impossible Quiche because even though you mix all of the ingredients together in one bowl, they will separate in pie pan in the oven to create two distinct layers. One bowl, a skillet, and one baking dish mean fewer dishes and less time in the kitchen.
  • A Delicious Breakfast or Brunch – Quiche recipes are perfect for those times that you want to serve breakfast or brunch to a group. This kid friendly recipe will serve 6 to 8 people and is easy to double up in two pie dishes if needed.
  • Versatile Recipe – Quiche is kind of like pizza in that the toppings are completely up to you! You can stick with my broccoli and cheese recipe, or add in your own favorite ingredients to make an entirely new dish.

If you’re looking for low carb option, try my crustless broccoli quiche instead!

Ingredients In Bisquick Impossible Quiche

Here’s what you need to make this easy breakfast casserole:

Complete list of ingredients and amounts can be found in the recipe card below.

  • Bisquick: This yellow box of baking mix has been a staple in home kitchens for generations now! Since the 1930s, a box of Bisquick was key to so many convenience recipes, and it still is today. You can make this recipe with the original mix, Heart Smart Bisquick, or gluten free bisquick baking mix.
  • Eggs: Of course we need eggs to make a quiche! This recipe uses just four eggs, since the crust layer is thicker than a traditional quiche has.
  • Broccoli and Cheese: Two cups of chopped broccoli florets are the perfect amount to add to this recipe. We will briefly cook the broccoli with some diced onion and minced garlic so that it’s crisp-tender.
  • Milk: Whole milk will make this quiche rich and creamy. You can use low-fat milk if that’s what you have on hand though.

How To Make Impossible Bisquick Quiche

Get ready by preheating your oven to 350°F (18ºC) or 160°C if using a fan oven, and adjust the oven rack to the bottom of the oven. Spray a 9 or 10-inch pie dish with non-stick spray and set aside.

  1. Mix the Eggs and Bisquick: In a large bowl, whisk together the eggs, milk, salt and pepper. Then add the Bisquick baking mix, and whisk until the mixture is completely smooth.
  2. Sauté Onions: Cook the onions in oil over medium-high heat until they are soft and translucent.
  3. Then the Garlic and Broccoli: Add the chopped broccoli and cook for 1 more minute, then add the garlic and cook for 30 seconds, or until fragrant. Remove the vegetables from the heat.
  4. Fill the Pie Plate: Add the vegetables to the prepared pie plate. Then sprinkle shredded cheese on top.

  1. Pour in the Bisquick Mixture: Whisk the bisquick and egg mixture briefly and then pour it all over the vegetables and cheese.
  2. Bake: Bake your impossible quiche in the preheated oven for 35 minutes, or until the quiche puffs up and the top is golden brown. Remove from the oven and let cool and set for at least 10 minutes before serving.

Tip!

The quiche will puff up in the oven and then deflate as it cools. This is normal! The quiche will look sort of wrinkly on top and will be delicious.

Recipe Tips

  • Edit the ingredients. I believe that the original recipe for Bisquick Impossible Quiche called for Swiss cheese and ham or crumbled bacon. You can try that, or replace the broccoli with other veggies such as bell pepper, spinach, asparagus, zucchini, or mushrooms. Whatever you decide to add, be sure that it’s cooked first before adding it to the egg mixture.
  • Use the low rack in your oven. This egg casserole cooks best if it’s set in the lower half of your oven to bake. This will ensure that the crust layer cooks fully and the top of the quiche doesn’t burn.
  • If the top browns too quickly, cover the dish with foil to finish baking.
  • To test for doneness, insert a toothpick into the center of the quiche. It should come out mostly clean, with maybe a few moist crumbs.
  • Give it time to cool. It will be difficult to slice this quiche into neat pieces while it’s hot from the oven. Let it cool and set for some time before serving.

Storing Tips

Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days.

Reheat slices in a toaster oven or your regular oven for just a few minutes. The quiche will be a bit soggy, but it is still tasty as a grab-and-go breakfast or a packed lunch option.

Freezer: This quiche can be frozen for up to 3 months, and it’s just as delicious when thawed and reheated again.

What To Serve With Quiche

Quiche is the perfect main dish for breakfast, brunch, or a light lunch! Try it with some of these other delicious brunch recipes:

  • Smoked Salmon Platter – Everyone can build their own smoked salmon bagel!
  • Cinnamon Coffee Cake, Cranberry Orange Scones, or Cheese Danish – For a sweet option.
  • Raspberry Sorbet Bellinis – To get the party started!

Recipe FAQs

Can I double the Recipe?

Yes! You can double the recipe and bake it in two pie pans or in one 9×13-inch baking pan.

How long should quiche rest before serving?

You should allow the Bisquick quiche to cool for at least 10 minutes, but it will be even easier to cut if you leave it for 15 minutes or more. This gives the eggs time to fully set.

    Very easy and delicious. I used some leftover roasted vegetables that I had on hand. I added cheddar and Gruyère cheese. It’s also pretty good reheated. Definitely a keeper.

    Delicious! I added a whole bulb of chopped garlic, a huge sweet onion & red pepper. I topped the sautéed veggies with about 2 cups of unchopped fresh organic baby spinach leaves then the cheese & batter.
