Egg Bake Recipe for Large Group: One-Pan Crowd-Pleasing Breakfast Feast

This egg bake recipe for large group transforms a simple one-pan breakfast into a stress-free feast that serves 12+ without sacrificing flavor or texture. The secret lies in layering eggs, cheese, and savory fillings in a 9x13-inch baking dish, then baking until golden and set—no flipping or fussing required. I've perfected this method for family gatherings, brunch parties, and holiday breakfasts where timing matters more than individual plating.

The beauty of this recipe is its flexibility: swap in ham for sausage, add spinach for greens, or keep it classic with just cheese and herbs. It bakes in 30 minutes at 375°F, making it faster than assembling individual omelets while feeding a crowd. The dish stays warm for hours, so you can focus on coffee and conversation instead of rushing to reheat.

What you'll end up with is a golden, custardy egg bake with crispy cheese on top and tender layers beneath—each slice packed with protein, flavor, and that satisfying "just-baked" aroma. The edges get slightly crispy, while the center remains creamy, ensuring every guest gets their favorite bite. It's the kind of breakfast that disappears quickly, leaving only empty plates and happy smiles.

For serving, pair with toasted baguette slices, a fresh fruit platter, or even a simple green salad to balance the richness. The recipe scales easily: double the ingredients for 24 servings, or use two baking dishes simultaneously. Make-ahead tip: Assemble the dish the night before and refrigerate—it bakes straight from the fridge without losing texture.

Ingredients for egg bake recipe for large group

Twelve eggs, two cups of cheese, and a handful of simple fillings—this crowd-sized breakfast bakes up golden and creamy every time.

The eggs are the foundation, so room temperature makes all the difference—they'll blend more smoothly and bake evenly. Kirkland Signature eggs from Costco are my go-to for large batches, but any large, high-quality eggs work. For the cheese, sharp cheddar from a block melts better than pre-shredded (which has anti-caking agents). If you're feeding a group with dietary restrictions, swap the sausage for turkey sausage or veggie crumbles—just keep the quantity the same. The bell peppers and onions can be prepped ahead and stored in the fridge for 2 days.

No sharp cheddar? Monterey Jack or pepper jack work just as well for a milder flavor. Running low on heavy cream? Half-and-half or whole milk will work in a pinch, though the texture will be slightly lighter. The dried chives can be swapped for 1 tbsp dried parsley if that's what you have. For extra flavor, add 1/2 tsp smoked paprika to the egg mixture. The garlic can be pre-minced or fresh—just don't skip it. If you're using a 9x13-inch glass baking dish, grease it with butter or spray with cooking oil for easy release.

This dish reheats beautifully—just cover with foil and warm at 350°F for 10-15 minutes. It keeps well in the fridge for 3 days, though I've never had leftovers that long. For a make-ahead crowd, assemble the dish the night before and refrigerate uncovered for 1 hour before baking—this helps the top get extra crispy. Portion into individual servings for easy grab-and-go breakfasts, or serve family-style with toast and fruit. The cheese gets extra crispy on top, so let it sit for 5 minutes before slicing.

Step-by-step instructions for an egg bake feeding a crowd

Here's the method for a simple, fast one-pan breakfast that feeds 12 without stress.

Start by dicing the 2 whole green bell peppers into ½-inch pieces and removing seeds to prevent bitterness. Thinly slice the 1 whole red onion into even rounds—this ensures it softens properly without disappearing into the dish. In a separate bowl, mix the 1.5 lbs cooked breakfast sausage with the 4 cloves minced garlic cloves and 1 tbsp dried chives for even distribution.

I like to work in batches here—chop the peppers first, then the onions while they rest. This prevents cross-contamination and keeps your prep area organized. If you're using fresh chives instead, finely chop them now and set aside. The garlic adds depth, but don't overdo it—too much can make the dish taste sharp rather than savory.

In a large bowl, whisk together the 12 whole large eggs until the yolks and whites are fully combined. Add the 2 cups heavy whipping cream, 2 cups milk, 1.5 tsp salt, and 1 tsp black pepper, whisking until smooth. This mixture should be uniform—no streaks of egg white or lumps of cream. The full-fat dairy creates a rich, custardy texture that holds up well for a crowd.

Next, fold in the 4 cups shredded sharp cheddar cheese using a silicone spatula. I use freshly shredded cheese from a block—pre-shredded varieties contain anti-caking agents that can make the final texture grainy. Add the prepped vegetables and sausage mixture, gently stirring to distribute everything evenly. The cheese should melt smoothly into the egg mixture, creating a cohesive batter.

Preheat your oven to 350°F. Grease a 9x13-inch baking dish thoroughly with the 2 tbsp melted butter, using a paper towel to spread it evenly along the bottom and sides. This prevents sticking and makes cleanup effortless. For extra insurance, I dust the pan lightly with the 2 tbsp all-purpose flour, tapping out any excess. The buttery, floured base ensures the egg bake releases cleanly without tearing.

Pour the egg mixture into the prepared pan and spread it evenly using a spatula. Tap the pan gently on the counter a few times to remove any air bubbles—this helps the bake set smoothly. The mixture should fill the pan to about ¾ full—it won't rise dramatically, so don't worry if it looks like too much. The key is even distribution for consistent cooking.

Place the baking dish in the preheated oven and bake for 35-40 minutes. You'll know it's done when the edges are golden brown and the center still has a slight wobble—it should jiggle like gelatin when gently shaken. Overbaking dries out the dish, so pull it out when it's just set. The internal temperature should reach 160°F at its thickest point.

If the top browns too quickly but the center isn't set, tent the pan with aluminum foil and return it to the oven for another 5-10 minutes. For a perfectly browned crust without drying, broil the dish for 2-3 minutes at the end—watch it closely to avoid burning. The cheese should be fully melted, and the sausage peppers should be tender but still recognizable.

Remove the egg bake from the oven and let it rest for 5-10 minutes before serving. This resting period allows the custard to firm up slightly, making it easier to slice and serve without falling apart. Use a sharp, long knife to cut the dish into 12 equal squares—this ensures everyone gets a fair portion of the cheesy sausage mixture.

Serve the egg bake warm, straight from the pan. The combination of creamy eggs, sharp cheddar, savory sausage, and sweet peppers creates a balanced flavor profile that satisfies a crowd. For extra flair, garnish each serving with a sprinkle of freshly ground black pepper and a pinch of dried chives. Leftovers? They reheat beautifully in the microwave or oven—just cover with foil to prevent drying.

Storing and reheating your leftovers

Fridge Storage

This egg bake stays fresh in the fridge for up to 3 days when stored properly. Let it cool completely before transferring to an airtight container—I use glass Pyrex with locking lids to maintain moisture. The flavors actually deepen overnight, so it's perfect for make-ahead breakfasts. Just reheat gently to preserve that creamy texture. ❄️

Freezer Prep

For longer storage, freeze individual portions in single-serving containers or wrap tightly in plastic wrap before placing in a freezer bag. Label with the date—it keeps for 2 months without texture loss. The key is to thaw overnight in the fridge before reheating. I find this works best for prepping ahead for busy mornings. 🧊

Reheating Methods

For the best results, reheat in the oven at 350°F for 10-15 minutes covered with foil. This method keeps the center creamy while warming through evenly. If using the microwave, cover with a damp paper towel and heat in 30-second intervals until warmed through—about 1-2 minutes total. The foil prevents drying out that golden crust. 🔥

Portion Control

Cut into 12 equal squares before storing to make serving easy. For individual breakfasts, package portions in small glass containers—they reheat perfectly in the microwave. The crispy cheese edges stay intact when reheated properly, giving that restaurant-quality texture every time. This is especially helpful for busy mornings when people grab and go. 🍽️

Make-Ahead Tip

Assemble the dish the night before and refrigerate uncovered for 1 hour before baking. This helps the top get extra crispy while keeping the inside perfectly set. It's a game-changer for brunch parties—just pop it in the oven while you set the table. The flavors meld beautifully overnight. 💡

Serving Warm

Serve immediately after baking for the best texture—each slice should be warm and gooey. Garnish with fresh herbs or extra black pepper right before serving. The warm, creamy egg bake pairs perfectly with toasted baguette slices or a fresh fruit platter to balance the richness. It's the kind of dish that disappears quickly! 🍴
