Ingredients for Savory Sausage and Spinach Breakfast Casserole

Ground pork sausage is the star of the dish, providing a savory and meaty base. You can use mild or spicy, depending on your preference. Fresh spinach adds a pop of color and nutrients; it wilts quickly and integrates beautifully into the casserole. Sharp cheddar cheese and mozzarella cheese offer a creamy, melty texture and a rich flavor. Eggs are the binding agent, creating that classic casserole texture. Whole milk adds richness and helps the eggs set smoothly. The seasoning — salt, black pepper, garlic powder, onion powder, and a touch of nutmeg — enhances the overall flavor profile, while butter brings everything together with a touch of indulgence. Finally, green onions add a hint of freshness that complements the richness of the dish.

Tips & Tricks

For a spicier kick, use hot sausage or add a pinch of red pepper flakes to the egg mixture.
If you don't have whole milk, a mix of half-and-half or even a plant-based milk can work in a pinch.
Make it ahead by assembling the night before and storing it in the fridge. Just bake it fresh in the morning.

Serving Suggestions

This casserole pairs wonderfully with a fresh fruit salad or a simple arugula side salad dressed with lemon and olive oil. If you're feeling indulgent, warm, flaky croissants are a delightful complement. For a complete brunch spread, consider adding a platter of smoked salmon or some crispy bacon on the side.

Frequently Asked Questions

Can I use frozen spinach?: Yes, just make sure to thaw and drain it well to avoid excess moisture in the casserole.
How long will leftovers keep?: Stored in an airtight container in the fridge, leftovers will keep for up to 3 days. Reheat in the oven or microwave before serving.

Savory Sausage and Spinach Breakfast Casserole Recipe Walkthrough

First, preheat your oven to 350°F (175°C). You want it hot and ready by the time your prep is done. In a large skillet over medium heat, brown the ground pork sausage until it's fully cooked; this should take about 8 minutes. Once cooked, drain any excess fat to keep the casserole from becoming greasy.

Add the butter to the sausage in the skillet. Once melted, stir in the chopped spinach and cook until it's wilted, which will only take about 2 minutes. This step will help to evenly distribute the flavors and ensure the spinach is tender.

In a large bowl, whisk together the eggs, milk, and seasonings: salt, black pepper, garlic powder, onion powder, and nutmeg. Make sure everything is well combined — the nutmeg might seem a bit unexpected, but it adds a subtle warmth that’s just lovely.

Grease a 9x13 inch baking dish to prevent sticking. Spread the sausage and spinach mixture evenly across the bottom of the dish. Next, layer the shredded cheddar and mozzarella cheeses over the sausage. This ensures that every bite is cheesy and delicious.

Pour the egg mixture over the cheese and sausage layers, distributing it as evenly as possible. Top it all off with the chopped green onions for a bit of fresh flavor.

Bake in your preheated oven for 40-45 minutes. You’ll know it’s done when the eggs are set and the top is a lovely golden brown. Allow the casserole to cool slightly before slicing and serving so that it holds its shape better.
