Sausage Croissant Breakfast Casserole

Welcome to the no-fuss but still kinda fancy breakfast zone. Today, we’re diving into a game-changer for brunch (or, let’s be honest… any other average breakfast situation): the Sausage Croissant Breakfast Bake. Think of it as the love child of a leisurely brunch and every day breakfast scramble. It’s decadent, it’s packed with flavor, and the best part is… it’s SO easy. Let’s break down how you can make your mornings a little more delicious without anyyyyy extra hassle.

The Lowdown on This Bake

First off, this isn’t your average breakfast casserole. We’re elevating things with buttery, flaky croissants, turning what would have been a standard egg bake into something you’ll be crushing on for the rest of the week. Add in some savory sausage, a couple of veggies for good measure, and a creamy egg mixture, and you’ve got yourself a dish that’s bound to impress.

What You’ll Need

  • Croissants: Grab a few from your local bakery or store. Day-old croissants are perfect for this โ€“ they soak up the egg mixture juuuust right.
  • Breakfast Sausage: Grab some fresh sausage from your local butcher shop or opt for your favorite brand at the supermarket. I like to use something with a bit of spice to jazz things up.
  • Eggs and Milk: The base of this croissant bake is made with fluffy eggs, whole milk, and a touch of heavy cream for richness.
  • Cheese: What would brunch be without cheese? It wouldn’t. I dig white cheddar and gruyere for this dish.

Here’s How To Make This Sausage Breakfast Croissant Bake:

Brown up your sausage and get your egg mixture ready.

Add half of the sausage, half of the cheese, and half of the croissants to the baking dish.

Bake for around 1 hour, until the croissants are crispy and the cheese is melted and browned on top. That’s it!

Why It’s a Winner

This dish is all about simplicity and flavor. It’s perfect for when you want something special without a ton of work, and it’s versatile. I love straightforward meal prep breakfasts like egg muffin cups most of the time, but this breakfast bake is a nice way to mix things up whenever I’m in a rut.

Make it ahead of time, pop it in the fridge, and just reheat when you’re ready to eat. Plus, it’s customizable. Not a fan of sausage? Swap it out for bacon or veggies. Love spice? Add some heat with jalapeรฑos or your favorite spicy sausage.

Serving It Up

This breakfast bake is pretty much a standalone star, but if you want to round out your meal, think about pairing it with some hash browns or some fresh fruit for something lighter. As for drinks, coffee is a no-brainer, but fresh orange juice is also a good bet.

    I am a sucker for breakfast sausage anything and I always make my own. This weekend was sausage making weekend so I kept some separate just so I could make this breakfast casserole. It’s so yummy and decadent, everyone demolished their portions right away. Now I wish I had made a double batch!

    • [email protected] on April 22, 2024 at 11:32 am

      You’re fancy! I’ve never tried making my own sausage but I bet this would make this next level. Thanks for commenting! ๐Ÿ™‚
