Kielbasa-Bagel Breakfast Casserole

 Kielbasa Bagel Breakfast Casserole from Noble Pig
What is it about the breakfast casserole that is just so appealing? Is it the ease and freedom it gives us in the morning because we've put it together the night before? Or is it the idea of waking up to a warm, comforting and cheesy breakfast that propels us to make these up on Saturday night?

I suspect it's a little of both. But, really, it's nice to have a breakfast you can just pop in the oven. The leftovers are also fantastic, so don't be afraid to make this even if you are not serving a crowd.

Using onion bagels really enhances the flavor and eliminates the use of a boatload of onions, which we see in lots of breakfast casserole recipes. This is also means you don't have to chop all of those onions...score for us!

It's really important to dry out your bagels...at least 24 hours on the counter. You'll end up with mush if you try to hurry this step. You can also dry them out in the oven if you need to speed up the process. Just make sure they are very stale.

This is how the casserole looks after sitting in the fridge overnight and soaking up the egg mixture, before adding the extra cheese on top.

Kielbasa-Bagel Breakfast Casserole

Recipe from: Created by Cathy Pollak for NoblePig.com | Serves: 10-12

Ingredients

  • 1 lb onion bagels, cubed
  • 1 Tablespoon vegetable oil
  • 1 package (14 oz) kielbasa, halved lengthwise and sliced
  • 10 oz sliced mushrooms
  • 1 large shallot, finely minced
  • 10 large eggs
  • 1 cup heavy cream
  • 1/2 cup whole milk
  • 1/2 cup beef broth
  • 1/2 cup spicy brown mustard
  • 1/4 cup sliced green onions
  • 1 teaspoon table salt
  • 1 teaspoon coarse black pepper
  • 8 oz shredded extra sharp cheddar cheese, divided

Directions

  • Stale bagel cubes on a baking sheet overnight (a good 24 hours really) until completely dry.
  • Preheat oven to 375 degrees and coat a 9 x 13 baking dish with nonstick spray.
  • In a nonstick pan over medium heat, brown kielbasa until edges are crisp. Remove with a slotted spoon onto a paper-lined plate. Add mushrooms and cook down until cooked and the water is cooked out of them (you might have to add a little more oil). Add shallot and cook until softened, about 1-2 minutes. Remove from heat.
  • In a large bowl whisk together eggs, cream, milk, broth, mustard, green onion, salt and pepper. Add bagel and toss to coat. Add kielbasa and mushroom-shallot mixture and half the cheese. Transfer to the prepared baking dish, cover and refrigerate overnight.
  • Sprinkle remaining cheese over the casserole and bake about 45-60 minutes or until an instant-read thermometer placed in the center reads 160 degrees F. Let sit 20 minutes before serving.

  1. I think all of your reasons we love breakfast casseroles are true! They’re so comforting yet easy, and free up our time particularly when we have visitors. I absolutely love them! Can’t wait to try this one, pinned the recipe!

  2. Never eaten a breakfast casserole. This one looks pretty tasty though. I guess they weren’t a thing in England when lived there and have never come across them over here and anyway I am usually too busy worrying about weight.

    Having made many breakfast casseroles with regular bread or Italian bread, I love the idea of the onion bagel base! And kielbasa instead of my usual ground sausage. Will definitely be making this in the near future. Breakfast casseroles are one of our favorites!
