Key Ingredients for Your Perfect Impossible Quiche

Crafting this delightful Broccoli 3-Cheese Impossible Quiche requires a handful of common ingredients that come together to create something truly special. Here’s what you’ll need, along with a few notes to ensure the best results:

  • Broccoli florets – We highly recommend using fresh broccoli for its superior texture and vibrant flavor. Chop them into small, bite-sized pieces so they cook evenly and distribute well throughout the quiche. While fresh is best, frozen broccoli can be used if thawed and thoroughly drained to prevent excess moisture.
  • Sharp cheddar cheese – Shredded. This cheese is the backbone of our cheesy flavor, providing a robust, tangy note that pairs beautifully with broccoli. Shredding your own from a block often yields a creamier melt compared to pre-shredded options.
  • Mozzarella cheese – Shredded. Known for its incredible melt and mild flavor, mozzarella adds a wonderful gooey texture to the quiche, binding the ingredients together harmoniously.
  • Parmesan cheese – Grated. A sprinkle of Parmesan brings a salty, umami depth that elevates the overall cheese profile. Freshly grated Parmesan will offer the most intense flavor.
  • Onion – Fresh onion, finely chopped. A small amount of finely chopped onion adds a subtle aromatic base and a hint of savory sweetness that enhances the other flavors without overpowering them.
  • Milk – We use whole milk for richness, but any milk variety you have on hand will work, though it may slightly alter the final texture.
  • Heavy whipping cream – This is key for achieving that luxurious, silky-smooth custard texture that defines a great quiche. Don’t skip it if you want the ultimate creamy experience.
  • Eggs – The essential binding agent that creates the custardy foundation of your quiche. Fresh, large eggs are always recommended.
  • Bisquick – The “impossible” magic ingredient! This pre-made baking mix acts as both a flour and a leavening agent, creating that unique, biscuit-like bottom crust without any effort.
  • Mustard powder – A secret ingredient that might surprise you! A touch of mustard powder doesn’t make the quiche taste like mustard, but rather enhances the savory flavors of the cheese and eggs, adding a subtle depth.

Essential Equipment You’ll Need

To make this Broccoli 3-Cheese Impossible Quiche a breeze, gather these basic kitchen tools:

  • Pie dish – A large, deep pie dish (9 or 10-inch) is ideal for accommodating the generous filling and ensuring a beautiful, tall quiche.
  • Baking sheet – Crucial for baking your quiche. A baking sheet with raised sides provides stability and catches any potential drips or spills during baking, keeping your oven clean.
  • Nonstick cooking spray – Essential for easily releasing your quiche from the pie dish without sticking.
  • Large mixing bowls – You’ll need two: one for combining the dry ingredients with the broccoli and cheese, and another for whisking the wet ingredients.
  • Whisk – For thoroughly blending the eggs and wet ingredients until smooth.

How To Make The Best 3-Cheese Broccoli Impossible Quiche

Follow these simple steps to create a show-stopping quiche that everyone will rave about. The beauty of this recipe lies in its straightforward process and delicious results!

  1. Prepare Your Oven & Dish: Begin by preheating your oven to a precise 400°F (200°C). This ensures the oven is at the correct temperature for even baking. Next, take your pie dish and generously spray the inside with non-stick cooking spray, covering all surfaces to prevent sticking. Place this prepared pie dish onto your baking sheet. The baking sheet is a safety measure to catch any overflow and makes transferring the hot quiche much easier.
  2. Chop the Broccoli: Take your fresh broccoli florets and chop them into small, uniform, bite-sized pieces. Consistency in size is key here for even cooking. Place these chopped florets into a large mixing bowl.
  3. Combine Dry Ingredients: To the bowl with the chopped broccoli, add your shredded sharp cheddar cheese, shredded mozzarella cheese, grated Parmesan cheese, and the finely chopped onion. Gently toss all these ingredients together until they are well mixed and the broccoli is evenly coated with the cheeses and onion. This ensures every slice of quiche is packed with flavor.
  4. Whisk Wet Ingredients: In a separate, medium-sized bowl, combine the eggs, milk, heavy whipping cream, and mustard powder. Add the Bisquick baking mix last. Whisk vigorously until all ingredients are thoroughly combined and the mixture is smooth, with no lumps of Bisquick remaining. This forms your creamy quiche custard.
  5. Marry the Mixtures: Pour the whisked wet ingredient mixture over the broccoli, cheese, and onion mixture in the large bowl. Stir everything together well, ensuring the custard evenly coats all the solid ingredients.
  6. Fill the Pie Dish: Carefully transfer the entire quiche mixture into your prepared pie dish. If you notice any broccoli florets floating on the very top, gently push them down into the custard with a spoon or spatula. This helps them cook through and prevents them from drying out.
  7. Bake to Perfection: With the pie dish still resting on the baking sheet, carefully place it into your preheated oven. Bake for approximately 60 minutes, or until the quiche appears uniformly puffy, golden brown on top, and fully set in the middle. You can test for doneness by inserting a knife into the center; if it comes out clean, your quiche is ready.
  8. Cool and Serve: Once baked, remove the quiche from the oven and allow it to cool slightly on the baking sheet for about 10-15 minutes before slicing. This cooling time allows the custard to fully set, making for cleaner cuts and easier serving. Then, cut into generous wedges and serve warm. Enjoy!

Chef Jenn’s Expert Tips for the Best Impossible Quiche

  • Use a Baking Sheet: Always bake your quiche on a baking sheet with raised sides. This isn’t just for ease of transport; it’s a crucial preventative measure. If your quiche happens to bubble over slightly while baking, or if you accidentally jostle it on the way into the oven, the baking sheet will catch any spills, saving your oven from a messy cleanup.
  • Don’t Overfill: Be mindful not to overfill your pie dish. The Bisquick-based batter will rise as it bakes, creating that delightful puffy texture. Leaving a small amount of headspace (about half an inch from the rim) will prevent overflow and ensure a perfectly domed quiche.
  • Prevent Over-Browning: If you notice the top of your quiche browning too quickly during the baking process, loosely cover the pie dish with a sheet of aluminum foil. This will protect the top from excessive browning while allowing the inside to continue cooking to perfection.
  • Utilize Broccoli Stems: Don’t discard those nutritious broccoli stems! They can absolutely be used in this recipe. Just make sure to peel the tougher outer layer and chop the stems into much smaller pieces than the florets. This ensures they soften and cook through at the same rate as the florets, adding extra texture and nutrients.
  • Experiment with Cheeses: While our three-cheese blend is fantastic, feel free to customize the cheese selection to your personal preference. You can mix and match your favorite cheeses – perhaps Gruyère for nuttiness, Colby Jack for a milder creaminess, or a spicy Pepper Jack for a kick. Just aim for approximately the same total volume of cheese for the best results.
  • Fresh Ingredients Matter: While convenience is key, using fresh, high-quality ingredients, especially fresh broccoli and good cheese, will significantly impact the final flavor and texture of your quiche.

Make It A Complete Meal

One of the many charms of quiche is its inherent completeness; a generous slice often suffices as a full, satisfying meal on its own. However, if you’re looking to elevate your dining experience and wondering what to serve alongside your delectable Broccoli 3-Cheese Impossible Quiche, here are some delightful suggestions to create a truly memorable spread:

  • Hearty Sides: For a more substantial meal, classic Home Fried Potatoes make an excellent, filling side dish. Their crispy texture and savory flavor perfectly complement the creamy quiche.
  • Baked Goods: Pair your quiche with a freshly baked treat like a savory Bacon, Cheddar, and Green Onion Scone. The flaky texture and rich flavors of the scone will add another layer of indulgence. Alternatively, a comforting Ham and Cheese Turnover offers a delightful contrast in texture and taste.
  • Fresh Salad: To lighten the meal, a crisp, simple green salad with a zesty vinaigrette would be a refreshing choice. The fresh greens provide a lovely balance to the richness of the quiche.
  • Fruit Platter: For breakfast or brunch, a vibrant fruit salad featuring seasonal berries, melon, and citrus segments adds a burst of freshness and natural sweetness.

Storage and Reheating Made Easy

This Broccoli 3-Cheese Impossible Quiche is just as delicious the next day, making it perfect for meal prepping or enjoying leftovers. Here’s how to properly store and reheat your quiche:

  • Refrigeration: To keep any leftover quiche fresh and flavorful, allow it to cool completely to room temperature first. Then, transfer the slices or the entire remaining quiche to an airtight container. Store it in the refrigerator, where it will remain fresh and delicious for 3-4 days.
  • Enjoying Leftovers: The beauty of this quiche is its versatility. You can enjoy your leftovers cold straight from the fridge, at room temperature, or gently reheated.
  • Reheating:
    • Microwave: For a quick reheat, place an individual slice on a microwave-safe plate and heat for 1-2 minutes, or until warmed through. Be careful not to overheat, as this can make the quiche rubbery.
    • Oven: For best results and to regain some of that initial crispness on the bottom, reheat larger portions or the entire quiche in the oven. Preheat your oven to 300°F (150°C). Place the quiche on a baking sheet and heat for 15-20 minutes, or until warmed through to the center. Covering it loosely with foil can prevent the top from browning further.
  • Freezing: While best fresh, quiche can also be frozen! Bake and cool completely. Wrap individual slices tightly in plastic wrap, then in foil, or place in freezer-safe bags or containers. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions (FAQs) About Impossible Quiche

Here are some common questions about making and enjoying Impossible Quiche:

  • Can I use frozen broccoli instead of fresh?
    Yes, you can! If using frozen broccoli, make sure to thaw it completely and drain any excess water thoroughly before adding it to the mixture. This prevents the quiche from becoming watery.
  • Can I prepare this quiche ahead of time?
    Absolutely! This quiche is excellent for making ahead. You can prepare and bake it completely, then store it in the refrigerator for up to 3-4 days. It can be enjoyed cold, at room temperature, or reheated.
  • Is this recipe gluten-free?
    The original recipe uses Bisquick, which contains wheat flour and is not gluten-free. However, you can substitute regular Bisquick with a gluten-free baking mix equivalent. Ensure all other ingredients are also certified gluten-free if dietary restrictions require it.
  • What if I don’t have heavy whipping cream?
    While heavy whipping cream provides the richest, most luxurious texture, you can substitute it with half-and-half or even a higher fat milk, like whole milk. The quiche will still be delicious, but the texture might be slightly less decadent.
  • Can I add meat to this quiche?
    Certainly! For a heartier meal, you can add cooked and crumbled bacon, ham, or sausage to the broccoli and cheese mixture before adding the wet ingredients. Ensure any meat is fully cooked and drained of excess fat.
  • How do I know when the quiche is fully cooked?
    The quiche is done when it’s uniformly puffed, golden brown on top, and set in the middle. A good test is to insert a knife or a wooden skewer into the center; if it comes out clean, your quiche is perfectly baked.
