Easy Leftover Stuffing Breakfast

Here is my favorite leftover stuffing breakfast recipe, with crispy edges, soft herbs, and whatever leftover stuffing you have sitting in your fridge from the night before.

This breakfast dish is my go-to solution when I can’t bear to throw away perfectly good stuffing after a big dinner. My kids actually get excited when they see me pulling out the leftover container because they know something good is coming. There’s just something special about turning yesterday’s side dish into today’s morning comfort food.

What Kind of Leftover Stuffing Should I Use?

Any leftover stuffing will work great for this breakfast recipe, whether it’s from Thanksgiving dinner or a weekend roast. The beauty of this dish is that it doesn’t matter if your stuffing is bread-based, cornbread, or even has sausage and herbs mixed in – they all add their own flavor to the final result. If your stuffing is really dry and crumbly, you might want to add an extra splash of milk to help everything come together. On the flip side, if your leftover stuffing is on the moist side, it will still work perfectly and might even make your breakfast extra rich and flavorful.

Options for Substitutions

This breakfast dish is all about using what you have, so feel free to make these swaps:

• Leftover stuffing: This is the star of the show, so you really need stuffing to make this work. If your stuffing is on the dry side, add a splash of chicken broth to moisten it up before using.
• Milk: Any milk works here – whole milk, 2%, or even half-and-half if you want it extra creamy. You can also use unsweetened almond milk or oat milk for a dairy-free option.
• Sharp cheddar cheese: Use whatever cheese you have on hand! Gruyere, Swiss, mozzarella, or even cream cheese all work great. Just make sure it melts well.
• Eggs: While you need eggs for this recipe to work, you can reduce the amount if you’re cooking for fewer people – just use about 2 eggs per cup of stuffing as a rough guide.

Watch Out for These Mistakes While Cooking

The biggest mistake when making leftover stuffing breakfast is using stuffing that’s too dry, which can result in a tough, crumbly dish – if your stuffing seems dry, add an extra splash of milk or even some chicken broth to moisten it up before adding the eggs. Don’t rush the cooking process by cranking up the heat, as this will scramble your eggs too quickly and leave you with a rubbery texture instead of a creamy, custard-like consistency. Make sure to stir gently and frequently over medium-low heat, and remove the pan from heat while the eggs still look slightly underdone since they’ll continue cooking from the residual heat. For extra flavor, try adding some leftover gravy or herbs from your holiday meal, and always taste and adjust the seasoning since leftover stuffing can sometimes lose its punch after sitting in the fridge.

What to Serve With Leftover Stuffing Breakfast?

This hearty breakfast dish is pretty filling on its own, but I love serving it with some crispy bacon or breakfast sausage on the side for extra protein. A simple fruit salad or fresh berries work great to balance out all those rich, savory flavors from the stuffing and eggs. If you want to keep the cozy breakfast vibe going, some buttered toast or English muffins are perfect for soaking up any runny egg yolk. A hot cup of coffee and maybe some orange juice round out this comfort food breakfast perfectly.

Storage Instructions

Refrigerate: This breakfast casserole keeps really well in the fridge for up to 4 days when covered tightly with foil or plastic wrap. It’s actually one of those dishes that tastes even better the next day after all the flavors have had time to meld together.

Freeze: You can definitely freeze portions of this for busy mornings! Cut it into individual squares and wrap each piece in foil, then store in a freezer bag for up to 3 months. It’s like having a homemade breakfast sandwich ready to go whenever you need it.

Warm Up: To enjoy leftovers, just pop a slice in the microwave for about 60-90 seconds, or warm it up in a 350°F oven for 10-15 minutes until heated through. From frozen, let it thaw overnight in the fridge first, then reheat as usual.

• Fat: 90-110 g
• Carbohydrates: 150-200 g

Ingredients

• 1/2 cup shredded cheese (I like Tillamook sharp cheddar)
• 4-5 cups prepared stuffing
• 10 large eggs (preferably organic, for richer yolks)
• 1/2 cup milk (whole milk for a creamier texture)

Step 1: Preheat the Oven and Prepare the Pan

Preheat your oven to 350°F (177°C).

While the oven is heating, lightly grease an 8×11.5-inch or 9×13-inch baking pan with cooking spray to prevent sticking.

Step 2: Layer the Stuffing in the Pan

• 4 to 5 cups prepared stuffing

Evenly spread the prepared stuffing in the bottom of the greased baking pan, creating a consistent layer.

If your stuffing is very dense or clumped, gently break it up for more even coverage.

Step 3: Mix the Egg Custard

• 10 large eggs
• 1/2 cup milk
• 1/4 cup shredded cheese

In a large mixing bowl, thoroughly whisk together the eggs, milk, and half of the shredded cheese until well combined.

This will ensure a uniform mixture for the casserole base.

Step 4: Assemble the Casserole

• egg mixture from Step 3
• stuffing from Step 2
• 1/4 cup shredded cheese

Pour the egg mixture from Step 3 evenly over the layer of stuffing in the pan.

Sprinkle the remaining shredded cheese over the top, making sure to cover the surface for a nicely browned topping.

I like to use sharp cheddar here for a stronger flavor, but feel free to experiment with your favorite cheeses.

Step 5: Bake the Casserole

Place the assembled casserole in the preheated oven and bake uncovered for 40-45 minutes, or until the eggs are fully cooked and the top is golden brown.

Once baked, allow the casserole to cool for a few minutes before serving for best texture.
