The cheesy sausage breakfast casserole that actually fixes your mornings.
No 6 a.m. panic. No sugar crash by 10. Just a golden, bubbling, sausage-and-cheddar bake you build once and eat all week — whether you’re feeding a hangry family of five or just trying to stay on track before your first meeting.
Mornings shouldn’t feel like damage control.
You know the drill: an alarm you’ve hit snooze on twice, a kid who “hates” the cereal they loved yesterday, and a fridge full of ingredients but zero minutes to use them. If you’re eating low-carb, add in the special misery of another sad hard-boiled egg. This casserole was built to break that cycle.
The old morning
- Standing over a pan scrambling eggs while everyone yells “are we late?”
- Grabbing a granola bar and being starving — and cranky — by 10 a.m.
- Falling off keto because plain eggs got boring around day four
- Cooking five separate breakfasts for five different moods
The new morning
- A pan you built Sunday night, already sliced and waiting
- 24g of protein a serving, so you’re steady until lunch, not snacking by 10
- Sausage, sharp cheddar and a rich, custardy base — nothing about it feels like “diet food”
- One dish, one dirty pan, breakfast for the whole table
Built for real kitchens, not food-blog kitchens.

One bowl, one pan
No layering, no par-baking, no fussy steps. Mix, pour, bake, done.
Naturally low-carb
No hash browns, no bread filler — just eggs, sausage, and cheese doing the heavy lifting.
Actually craveable
Cream cheese and cottage cheese in the base keep every bite fluffy instead of rubbery.
Feeds the whole table

- 1.5 lb (680 g) breakfast sausage, casings removed
- 10 large eggs
- 1 cup (240 ml) heavy cream

- 2 cloves garlic, minced
- 1 tsp smoked paprika
- 1/2 tsp onion powder, plus salt & pepper to taste
- 2 tbsp fresh parsley, chopped, for garnish
Swap it your way
- No pork sausage?
- Ground turkey or chicken sausage both work — add 1 tbsp olive oil since they’re leaner.
- Skip the cottage cheese
- Blend it into the egg mixture if you don’t love the texture, or swap in an extra 1/2 cup cream cheese.
- Dairy-free?
- Use a dairy-free cream cheese and shredded cheddar alternative; coconut cream in place of heavy cream.
- Want it spicy?
- Swap cheddar for pepper jack and add a diced jalapeño with the sausage.
- Not strict keto?
- Fold in 1.5 cups thawed shredded hash browns for a heartier, family-style bake.
Six steps. One golden pan.

Prep the pan
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish generously with butter or nonstick spray — this base gets custardy, and you don’t want any sticking.
5 minBrown the sausage
In a large skillet over medium-high heat, cook the sausage, breaking it into small crumbles, until no longer pink, about 7–8 minutes. Add the garlic in the last minute. Drain excess fat and set aside to cool slightly.
8 minBuild the custard base
In a large bowl, whisk the eggs, heavy cream, cubed cream cheese, cottage cheese, smoked paprika, onion powder, salt and pepper. It’s fine if the cream cheese stays a little lumpy — it melts into pockets of richness as it bakes.
Combine and pour
Stir the cooked sausage, half the cheddar, and half the green onions into the egg mixture. Pour everything into your prepared dish and spread into an even layer.
Top and bake
Sprinkle the remaining cheddar evenly over the top. Bake for 35–40 minutes, until the center is set (a knife inserted comes out clean) and the top is deeply golden and bubbling at the edges.
35–40 minRest, garnish, slice
Let the casserole rest 10 minutes before slicing — this is what gives you clean, holds-its-shape squares instead of a scramble. Top with parsley and the remaining green onions, then serve warm.

Get it right the first time.
Prep it the night before
Assemble completely, cover, and refrigerate up to 24 hours. Bake straight from the fridge — just add 5–8 extra minutes.
Freeze it in squares
Cool completely, slice, and freeze in a single layer before bagging. Grab one square at a time all month.
Spice it up
A diced jalapeño and a swap to pepper jack turns this into a genuinely fiery brunch centerpiece.
Sneak in vegetables
Sautéed spinach, bell pepper, or mushrooms fold in beautifully with the sausage — squeeze out excess liquid first.
Pick a cheese that melts
Sharp cheddar gives flavor, but a handful of Monterey Jack mixed in gives you that stretchy, pull-apart top.
Know when it’s done
The center should jiggle only slightly, not slosh. It firms up more as it rests, so don’t wait for it to be rock solid.

You asked, we answered.
Absolutely — fold in 1.5 cups of thawed shredded hash browns with the sausage in step 4. It stretches the casserole further and adds a heartier, more traditional texture.
This usually means it needs a few more minutes in the oven, or that added vegetables released extra liquid. Sauté and drain any vegetable add-ins well before mixing them in, and always check the center with a knife before pulling it out.
Yes — use a dairy-free cream cheese, a plant-based shredded cheddar, and full-fat coconut cream in place of the heavy cream. The texture will be slightly less rich but still holds together well.
Insert a knife into the center — it should come out clean, and the top should be deeply golden with slightly crisped edges. A gentle jiggle in the very center is normal and will firm up during the 10-minute rest.
Yes — use the servings toggle above the ingredient list to scale to 20 servings, then split the mixture between two 9×13 dishes rather than overfilling one pan, which can leave the center undercooked.
Any bulk breakfast sausage works — mild, hot, maple, or Italian all bring a different personality to the bake. Just make sure it’s fully browned and drained before mixing it in, so the finished casserole isn’t greasy.
