This sausage, egg, and cheese bake recipe stands out for me because of its versatility and customizability. It’s not just a breakfast and brunch option but can make a great comforting dinner with garlic bread or breakfast potatoes on the side.

Ingredients

See the recipe card for exact amounts.

Ingredients for an egg bake labeled eggs, mushrooms, peppers & onions, garlic, cheese, and fully cooked sausages.
  • Eggs: Large eggs are the base for this recipe.
  • Sausages: I use fully-cooked plant-based sausages because it’s what I prefer and I like the Classic Smoked Sausages by Field Roast. You can absolutely use whatever you prefer. See substitutions below.
  • Cheese: Sharp cheddar brings a tangy richness that complements the eggs and sausage perfectly.
  • Vegetables: I use frozen bell pepper and onion strips to make it easy. I also use fresh mushrooms. Make sure to cook any vegetables with high water content like bell peppers and mushrooms. This takes about 10 minutes and it’ll take about 7-8 minutes to draw out the moisture and then another few minutes to cook the moisture away.

Substitutions

  • Sausages: If using a sausage with ground meat, make sure to cook the sausages fully before adding them to the egg mix.
  • Vegetables: Try adding sautéed spinach or kale.
  • Cheese: Experiment with different cheeses like pepper jack for added spice.

Meal Prep Tip

This recipe keeps well in the fridge and reheats easily, making it great for meal prep. Store in an airtight container, zip top bag, or wrapped tightly in plastic wrap.

Prep Tips

  • Preheat the oven to 400°F.
  • Oil a 9 x 13 sheet pan.

Once you cook the vegetables and slice the sausage the recipe is ready to put together and bake – very easy prep!

  1. Cook the vegetables in a pan (about 10 minutes). It’ll take about 6-8 minutes to draw out the moisture from the mushrooms and then the moisture will cook off. Cook the garlic in the last minute or so. The veg is then ready to add to the baking pan.

Let the egg bake cool for about 5 minutes in the pan and then slice and serve.

I like mine with a generous drizzle of sriracha sauce but I bet ketchup would also be a good no-spice option.

Tips for making a baked egg casserole

  • Sauté the vegetables to remove excess moisture and prevent a soggy bake.
  • Use fully cooked sausage to ensure they are cooked in the final dish, or if using ground sausage, cook it before adding to the egg.
  • Grease your baking dish well: A well-greased dish prevents a lot of sticking and makes serving much easier – trust me I found this out during testing! Eggs still tend to stick to the pan a bit.

What to serve with a sausage egg and cheese bake

I love this simple bake for breakfast just on its own with hot sauce.

For a quick weeknight dinner, serve the egg bake alongside roasted vegetables, smashed potatoes, a quick sauté of seasonal greens, or a simple side salad dressed in a light vinaigrette. 

If you’re hosting a brunch gathering or a casual weekend get-together, serve this dish with garlic toast, fresh fruit, or a vibrant breakfast salad.

An easy and satisfying breakfast recipe, great served when made or perfect for meal prep.

Ingredients
  

  • 8 large eggs
  • 4 fully-cooked sausages see notes*
  • 1 ½ cups shredded cheddar cheese I use sharp cheddar
  • 2 cups bell pepper and onion strips
  • 1 cup sliced mushrooms or 6-8 large bellas
  • 3 cloves garlic minced
  • ½ teaspoon kosher salt
  • black pepper

Instructions

  • Preheat the oven to 400°F (200℃). Grease a 9 x 13 baking dish.
  • Heat a skillet over medium and sauté the mushrooms, bell pepper, and onions for about 10 minutes. Season with salt and pepper. After 8 minutes the moisture should be drawn out and start to cook off. Add the garlic in the last minute of cooking and then transfer to the prepared baking dish.
  • Add the sliced sausages on top of the vegetables and spread evenly.
  • In a medium bowl, whisk the eggs and season with salt and pepper. Pour into the baking dish.
  • Scatter the cheese on top, poking it into the egg mix in places. This way you'll have soft melty cheese inside to contrast with the baked cheese on top.
  • Bake for 20 minutes or until the eggs are fully cooked.
  • Let cool for 5 minutes and then slice and serve.

Notes

* I used fully cooked plant-based sausages. If using sausages with ground meat or other sausages that are not fully cooked, make sure to cook them before adding them to the bake.
