Ingredients

For this sausage breakfast bake, you’ll work with two simple groups of ingredients. First, the savory base — pork sausage, diced red pepper, onion, and chopped spinach build layers of flavor.

• Wooden spoon or spatula
• Measuring cups and spoons
• Cooking spray or butter (for greasing the dish)

Step-by-Step Instructions

Making this Sausage Hash Brown Breakfast Bake is as simple as brown, mix, and bake. Let’s walk through it together.

Step 1: Preheat and Prep. Preheat your oven to 350°F. Lightly grease a 9×13 inch baking dish with cooking spray or a little butter. Set it aside while you cook the filling.

Step 2: Cook the Sausage and Veggies. Heat a large skillet over medium-high heat. Add the 1 lb of pork breakfast sausage, 3/4 cup diced onion, and 3/4 cup diced red pepper. Break up the sausage into small crumbles as it cooks. Keep going until the veggies are soft and the sausage is fully cooked with no pink remaining — about 7–9 minutes. Drain any excess grease from the pan.

Step 3: Wilt the Spinach. Add 1–2 cups of finely chopped spinach to the hot skillet. Stir it in and cook for another 1–2 minutes until wilted. Remove the skillet from the heat and let the mixture cool slightly before the next step.

Step 4: Mix the Egg Custard. In a large bowl, whisk together 10 large eggs, 1/2 cup of whole milk (or coconut milk), 1 tsp kosher salt, 1/2 tsp pepper, 2 cups of frozen hash browns, and 1 cup of shredded sharp cheddar. Add the cooled sausage mixture and stir until everything is evenly combined.

Step 5: Assemble and Top. Pour the mixture into your greased 9×13 baking dish. Spread it out evenly, then top with an extra sprinkle of shredded cheddar. At this point, you can either bake it right away or cover it and refrigerate overnight.

Step 6: Bake to Perfection. Bake uncovered at 350°F for 25–30 minutes, until the eggs are fully set and the cheese is golden and bubbly. Your kitchen is going to smell absolutely amazing. Let it cool for a few minutes before slicing and serving. Enjoy!

Pro Tips for the Best Brunch Casserole

This brunch casserole is pretty forgiving, but a few small tweaks can take it from great to absolutely incredible. These are the things I’ve learned from making it again and again.

Don’t skip draining the sausage. After cooking, drain off any excess grease from the skillet before adding the spinach. Extra grease can make the casserole greasy and heavy — and nobody wants that.

Let the sausage mixture cool before mixing in the eggs. Adding hot meat to your egg mixture can start cooking the eggs prematurely. Give it just 5–10 minutes to cool down first.

Use frozen hash browns straight from the bag. No need to thaw them first. They’ll cook through perfectly in the oven, and skipping the thaw step saves time.

Add extra cheese on top. Don’t be shy with it. A generous handful of cheddar on top creates the most gorgeous golden, bubbly crust when it bakes.

Quick Fixes for Sausage Hash Brown Breakfast Bake

Even the easiest recipes sometimes need a little troubleshooting. Here’s how to fix the most common hiccups.

Eggs are still runny in the center? Pop it back in the oven for 5-minute intervals until fully set. Every oven runs a little differently, so check at the 25-minute mark and add time as needed. The center should jiggle slightly but not be liquid.

Casserole is too watery? This usually happens if the sausage grease wasn’t drained well, or if the spinach released too much moisture. Make sure to drain the skillet and pat any very wet veggies dry before mixing everything together.

Top is browning too fast? Lay a loose piece of aluminum foil over the dish for the last 10 minutes of baking. This shields the cheese without trapping steam, so the eggs still set properly.

Hash browns are a bit mushy? Be sure you’re using frozen (not thawed) hash browns. Thawed or pre-cooked hash browns release extra moisture and can turn soft during baking.

Variations and Adaptations

This sausage breakfast bake is wonderfully flexible. Swap and swap away — it’s nearly impossible to mess up.

Dairy-Free: Use unsweetened coconut milk in place of whole milk and swap the cheddar for your favorite dairy-free shredded cheese. It works beautifully.

Spicy Kick: Use hot Italian sausage or add a pinch of red pepper flakes to the egg mixture. It wakes the whole dish right up.

Extra Veggie: Throw in diced zucchini, mushrooms, or sun-dried tomatoes alongside the peppers and onion. More veggies, more color, more flavor.

Chicken Sausage: A lighter swap that still delivers great flavor. Look for a fully seasoned variety for the best result.

Southwest Style: Add black beans, a handful of diced green chiles, and swap cheddar for pepper jack. Top with fresh salsa after baking. If you love bold flavors like this, you’ll also love this meal-prep Southwest chicken salad jar recipe for easy weekday lunches.

Serving, Storage, and Reheating

This sausage breakfast bake is best served warm, right out of the oven. Cut it into squares and serve alongside fresh fruit, sliced avocado, or a simple green salad for a complete brunch spread. It also pairs beautifully alongside a fun deviled egg board if you’re hosting a crowd.

Storage: If you somehow manage not to eat the whole thing in one sitting, store leftovers in an airtight container in the refrigerator for up to 4 days. It keeps really well and makes the most incredible weekday breakfast.

Reheating: Individual slices reheat wonderfully in the microwave in about 60–90 seconds. For a slightly crispier result, pop a slice in the air fryer at 325°F for 4–5 minutes. It’s just as good the next day, honestly maybe better.

No-Waste Kitchen Magic

Got leftover sausage breakfast bake? Use it creatively so nothing goes to waste.

Breakfast wrap: Slice a square, warm it up, and wrap it in a flour tortilla with a little hot sauce. Instant breakfast burrito — better than anything drive-through.

Grain bowl topping: Crumble leftover casserole over a bowl of brown rice or quinoa with sliced avocado and a drizzle of hot sauce for a satisfying lunch.

Freeze it: This bake freezes well. Wrap individual slices in plastic wrap and store in a zip-top bag for up to 2 months. Thaw overnight in the fridge and reheat in the oven or air fryer.
