Father’s Day Breakfast Casserole With Sausage and Hash Browns

This sausage and hash brown breakfast casserole is built for a Father’s Day brunch where you would rather sit at the table than stand at the stove. It uses five ingredients: 1 pound of breakfast sausage, 8 eggs, 2 cups of cheddar, 3 cups of frozen hash browns, and salt and pepper. It takes 15 minutes to prepare and 35 minutes to bake, and one dish serves 8.

Because everything bakes together in one pan, it stays warm while people help themselves. That leaves the morning free for a quick sweet dish, a fruit platter and coffee.

Ingredients

• 1 lb breakfast sausage: Bulk sausage is easiest because you can crumble it straight into the pan. Links work too; slice or squeeze them out of their casings first. Mild, sage or hot sausage all fit; the choice sets the flavor of the whole casserole.
• 8 large eggs: They bind the casserole. Whisk them until no streaks of white remain, so the texture sets evenly instead of in patches.
• 2 cups shredded cheddar cheese: Sharp cheddar gives the most flavor. Shredding your own from a block melts more smoothly than pre-shredded cheese, which has an anti-caking coating.
• 3 cups frozen hash browns (or roasted potatoes): Shredded or diced both work. Leftover roasted potatoes give a firmer, chunkier bite.
• Salt and pepper: Season lightly, because the sausage and cheese are already salty.

How to Assemble and Bake the Casserole

1. Brown the sausage

Cook the sausage in a skillet over medium heat, breaking it into small crumbles, until it reaches 160°F. Use a thermometer rather than judging by color. Drain off most of the fat so the casserole doesn’t turn greasy.

2. Layer the potatoes and sausage

Heat the oven to 350°F and grease a baking dish large enough for 8 servings. Spread the hash browns in an even layer, then scatter the sausage over them and about half the cheddar.

3. Add the eggs

Whisk the eggs with a pinch of salt and pepper and pour them evenly over the layers. Press down gently with a spatula so the potatoes are coated. Top with the remaining cheddar.

4. Bake and rest

Bake for about 35 minutes, until the edges are golden and a knife inserted near the center comes out clean. Egg dishes are done at 160°F in the center. Let the casserole rest for about 10 minutes before cutting; the eggs firm up and the squares hold their shape.

Why Breakfast Casseroles Turn Out Soggy or Dry

• Watery middle: Frozen hash browns release moisture as they thaw. Spread them on a towel and pat them dry first, or bake them straight from frozen in a thin, even layer and allow a few extra minutes.
• Greasy pan: The sausage fat wasn’t drained. Tip the skillet and spoon off the fat before layering.
• Rubbery, dry eggs: The casserole baked too long. Start checking a few minutes early and take it out once the center is set and has reached 160°F.
• Pale, soft top: Save half the cheese for the top so it browns, and use a light metal or glass dish rather than a deep one.

Swaps and What to Expect

• Bacon or diced ham instead of sausage: Bacon gives a smokier, saltier casserole; ham is milder and doesn’t need browning.
• Pepper jack or Colby jack instead of cheddar: Pepper jack adds heat; Colby jack melts softer and tastes milder.
• Diced peppers and onions: Sauté them with the sausage so they don’t release water into the eggs. Expect a slightly softer set.
• Tater tots instead of hash browns: A crisper top and a more rustic look. Lay them in a single layer.

Make It the Night Before

For a relaxed Father’s Day morning, assemble the casserole the evening before, cover it and refrigerate. In the morning, let it sit on the counter while the oven heats and add about 5–10 minutes to the baking time, because it goes in cold. Check that the center reaches 160°F.

Refrigerate leftovers within 2 hours and eat them within 3–4 days. Reheat single squares in the microwave or the whole dish covered in a 350°F oven until the center reaches 165°F.

Building the Rest of the Brunch Table

The casserole covers the savory main, so the rest of the table can stay simple. A useful rule is one main, one sweet dish, one fresh side and one drink.

• Something sweet: Pancakes, waffles or a baked French toast balance the salty sausage and cheese. If you make pancakes for a group, keep them warm on a wire rack in a 200°F oven so they don’t steam.
• Something fresh: A fruit platter or yogurt with berries. Slice the fruit the night before and keep it chilled.
• Extras on the side: Hot sauce, salsa, chopped herbs and warm biscuits let everyone adjust their plate.
• Drinks: Coffee or cold brew, orange juice and sparkling water with citrus cover most tastes.

More ideas for the day

If you want to build a bigger menu, a few other recipes fit a Father’s Day brunch. For a second savory dish, the steak and potato breakfast hash cooks in one skillet, and the steak, egg and cheese bagel suits a dad who likes a hearty sandwich. For the sweet side, the rhubarb coffee cake with crumb topping uses a fruit that is in season in June and can be baked the day before. To add a drink for the adults, a peach bellini takes a few minutes to blend.

FAQ

Can I add milk to the eggs?

The recipe doesn’t call for it. A splash of milk gives a slightly softer, more custardy set, but more than a few tablespoons can make the middle watery.

How do I keep the casserole warm while serving?

Hold it in a 200°F oven, loosely covered with foil so it doesn’t dry out. Hot food should stay at 140°F or above and shouldn’t sit at room temperature for more than 2 hours.

Can I freeze breakfast casserole?

Yes, after baking. Cool it, cut it into squares, wrap them well and freeze. Thaw overnight in the fridge and reheat to 165°F. Expect the potatoes to be a little softer.

Can I halve the recipe?

Yes. Use half of each ingredient in a smaller dish. A thinner layer may set a few minutes sooner, so start checking early.
