Breakfast & Brunch
This Big Green Egg lasagna recipe transforms your morning into a savory, crispy-crusted breakfast masterpiece—no oven required. The secret lies in grilling layers of fluffy hash browns, cheesy egg casserole, and runny yolks that turn every bite into a golden, gooey delight. After years of perfecting outdoor lasagna, I’ve cracked the code for achieving that crispy crust and fast assembly on your Big Green Egg.
The magic happens with a cast-iron skillet or grill-safe pan, where indirect heat cooks the layers evenly while keeping the edges crispy and the center creamy. Unlike traditional oven lasagna, this version relies on the Egg’s heat retention to melt cheese perfectly and set the crust without drying out. Preheat your Egg to 375°F, then layer your ingredients in a foil-lined pan for easy cleanup and moisture control.
By the time you’re done, you’ll have a breakfast casserole with a crispy top crust, tender hash browns, and eggs so runny they’ll pull apart with every forkful. The Big Green Egg’s even heat ensures no cold spots, and the smoky char from the grill adds a depth you won’t find in the oven. This is the kind of dish that turns weekend mornings into a feast.
Serve with a side of crispy bacon or fresh herbs for extra flavor. The best part? It’s ready in under an hour, with minimal prep and maximum flavor. Let’s get grilling!
Ingredients for big green egg lasagna
Six layers of crispy, cheesy, eggy goodness—no oven needed for this Big Green Egg masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 12 whole | Room temperature for even cooking |
| Shredded Hash Browns 🥔 | 2 cups | Freshly grated or frozen thawed |
| Shredded Cheddar Cheese 🧀 | 2 cups | Sharp cheddar preferred for flavor |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| All-Purpose Flour 🌾 | ¼ cup | For crispy crust texture |
| Bacon Crumbles 🥓 | 1 cup | Cooked crispy for topping |
| Fresh Chives 🌿 | ¼ cup | Chopped for garnish |
| Salt 🧂 | 1 tsp | Kosher salt preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | 1 tsp | For depth of flavor |
| Olive Oil 🫒 | ½ cup | For greasing pan and crispy crust |
| Heavy Cream 🥛 | ½ cup | For creamy texture |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty for easy handling |
The hash browns are your crispy crust foundation. Frozen thawed works best—skip the pre-shredded bagged stuff, it gets soggy. I grab the Ore-Ida Golden Crinkles from Costco when I'm doing a big batch, but any frozen hash browns will do. For extra crunch, toss them with a pinch of salt before grilling. The eggs? Room temperature is key—they cook more evenly and stay runnier. Crack them into a bowl first to avoid shell surprises.
No sharp cheddar? Pepper jack or Monterey Jack works in a pinch, but sharp cheddar gives that signature tang. Swap the heavy cream for half-and-half if needed, but trust me on the full-fat version for that creamy texture. Bacon crumbles can be store-bought or homemade—Trader Joe's has great pre-cooked ones, but homemade stays crispier. Fresh chives add brightness, but dried works at half the amount if you're in a bind. The garlic powder is non-negotiable here—it's what makes this taste like breakfast, not just scrambled eggs.
Prep ahead for foolproof grilling. Mix the egg-cheese sauce the night before and store it covered in the fridge. The hash browns can be pre-grilled and kept warm in a 200°F oven while you assemble. This keeps 3-4 days in the fridge, but honestly, it reheats even better the next day. For leftovers, wrap tightly in foil and reheat on the Egg at 350°F for 10 minutes—the crust gets crispy all over again.

Step-by-step instructions for breakfast casserole with crispy crust and runny yolk magic
Here's how to build this hearty breakfast casserole with a golden crust and perfect runny yolks.
Prep the Crispy Crust Mixture
In a large bowl, whisk together the 12 whole large eggs, 1 cup milk, 0.25 cup all-purpose flour, 1 tsp salt, 0.5 tsp black pepper, and 1 tsp garlic powder until fully combined. This mixture forms the creamy base of your casserole. I like to whisk for about 1 minute to ensure everything is well incorporated—you'll notice the batter thicken slightly as it sits.
In a separate bowl, gently fold in the 2 cups shredded hash browns and 2 cups shredded cheddar cheese using a spatula. Be careful not to overmix—just combine until the hash browns are evenly distributed. The hash browns will add that crispy texture we're after, while the cheese melts into a rich, gooey layer.
Assemble the Casserole Layers
Preheat your oven to 375°F while you prepare the rest. Lightly grease a 9x13-inch baking dish with 0.25 cup olive oil (about 2 tablespoons) to prevent sticking. Spread half of the egg mixture evenly into the bottom of the dish, pressing down gently with a spatula to create an even layer.
Sprinkle half of the 1 cup bacon crumbles and half of the 0.25 cup chopped fresh chives over the first layer. Then add the remaining egg mixture, followed by the rest of the bacon and chives. This layering ensures every bite has crispy bacon and fresh herbs in every forkful. The chives add a bright, fresh contrast to the rich eggs and cheese.
Bake Until Golden and Set
Cover the baking dish tightly with the 1 sheet aluminum foil and bake for 35 minutes. This initial covered bake allows the casserole to set without forming a crust too quickly. After 35 minutes, remove the foil and increase the oven temperature to 400°F for the final 15-20 minutes until the top is golden brown and crispy.
You'll know it's done when the edges pull away slightly from the pan and the top has a deep golden color. The center should still be slightly jiggly—this ensures those perfect runny yolks when you cut into it. If the top browns too quickly, tent loosely with foil for the last few minutes to prevent over-browning.
Add Creamy Finishing Touch
Once the casserole is golden and crispy, remove it from the oven and immediately stir in the 0.5 cup heavy cream using a spatula. This step adds that luxurious creaminess that makes this casserole extra special. The cream will melt into the warm eggs, creating a velvety texture that contrasts beautifully with the crispy top.
Let the casserole rest for 5 minutes before serving. This resting time allows the layers to set slightly, making it easier to slice without everything falling apart. The contrast between the crispy top, creamy center, and runny yolks is what makes this breakfast casserole truly magical.
Serve With Fresh Herbs
Cut into 6 equal squares (since this serves 6) and garnish each portion with an extra sprinkle of fresh chives. The chives add a pop of color and fresh flavor that cuts through the richness of the eggs and cheese. Serve immediately while the top is still crispy and the yolks are perfectly runny—this is when it tastes best!
For an extra crispy top, broil for 1-2 minutes right before serving, but watch closely to avoid burning. This casserole is perfect for brunch or a hearty breakfast that feeds a crowd. The combination of textures and flavors makes every bite satisfying and delicious.
Pro Tips For Making Big Green Egg Lasagna
- Pre-Cook the Hash Browns: Drain and pat those shredded hash browns thoroughly—no one likes a soggy lasagna. Spread them on a baking sheet, sprinkle with a pinch of salt, and bake at 375°F (190°C) for 10 minutes before assembling. This step cuts down on grease and keeps your layers crispy instead of mushy.
- Whisk Eggs Like a Pro: Beat the eggs and milk vigorously until the mixture is thick enough to coat the back of a spoon—this isn’t a smoothie. A hand mixer works, but elbow grease (yes, even if you’re impatient like me) ensures the lasagna binds properly without turning gummy.
- Layer Cheese Evenly: Skip the random sprinkle—divide the shredded cheddar into three equal piles for each layer. Press it down lightly with a spatula so it melts into a cohesive blanket, not just a pile of cheese on top. Trust me, the first bite will be worth the effort.
- Bake Until Bubbling Stops: Cover the lasagna with foil for the first 30 minutes, then uncover and bake another 15–20 minutes—until the edges are golden and the center no longer jiggles when you shake the pan. Overbaking dries it out; underbaking leaves it raw. Use a thermometer if you’re unsure (170°F/77°C at the center is ideal).
Storing and reheating your leftovers
Big Green Egg Storage
Store leftovers in an airtight container (I use Glasslock containers) for up to 4 days in the fridge. The Big Green Egg’s cast-iron skillet or foil-lined pan keeps this casserole crispy longer than oven-baked versions. Wrap tightly in heavy-duty aluminum foil to preserve that golden crust and prevent drying out. For best results, reheat directly on the Egg—no oven needed! 🌡️
Freezer-Friendly Method
This lasagna freezes beautifully for up to 3 months. Assemble the dish as directed, then wrap it completely in two layers of heavy-duty foil before placing it in a freezer bag. When ready to eat, thaw overnight in the fridge, then reheat on the Big Green Egg at 350°F for 20-25 minutes until the crust is crispy again. The eggs stay creamy, and the hash browns retain their crunch.
Reheating on the Egg
For the crispiest results, place your stored lasagna on the preheated Big Green Egg (set to 350°F) in a cast-iron skillet or directly on the grill grate. Cover with foil and heat for 15-20 minutes, then remove the foil for the last 5 minutes to restore that golden crust. A quick spray of olive oil before reheating adds extra crispiness. Pro tip: Add a splash of milk or heavy cream if it looks dry.
Microwave Backup Plan
If you’re in a hurry, microwave individual portions on 50% power for 2-3 minutes, then cover with a damp paper towel and microwave another 30 seconds. Stir in 1 tablespoon of milk to restore creaminess. While not as crispy, this method still delivers that rich, cheesy goodness when you’re short on time. 🔥
Leftovers Hack
Turn cold leftovers into crispy breakfast tacos! Slice the casserole into 1-inch squares, heat in a cast-iron skillet on the Egg until golden, then serve in warm tortillas with sour cream and salsa. The contrast of textures makes this a next-day favorite. Store leftovers in single-serving portions for easy grab-and-go breakfasts during the week.

Frequently asked questions
Can I make this Big Green Egg lasagna without hash browns?
Swap the hash browns for 2 cups shredded potatoes (like Yukon Gold) or 1 cup crushed potato chips for extra crunch. For a grain option, try 1 cup cooked quinoa or couscous—just reduce the milk by 2 tablespoons to maintain the right texture. The key is keeping that crispy element, so toasting your substitute first helps.
How do I adjust the recipe for a smaller Big Green Egg?
For a 12-inch Egg, halve the recipe and use a 9-inch cast-iron skillet instead of a baking dish. Cook at 350°F for 25 minutes covered, then 15 minutes uncovered to get that crispy top. The smaller surface area means you'll need to watch it closely to prevent over-browning. A 18-inch Egg can handle the full recipe with room to spare.
Why did my lasagna turn out dry instead of creamy?
Overcooking is the #1 cause—this dish is best when the center is still slightly jiggly. Use an instant-read thermometer: the internal temp should reach 160°F (not 180°F+). Also check your foil coverage—if gaps let heat escape, the moisture evaporates faster. For extra creaminess, stir in 2 tablespoons milk before serving or reheat with a splash of heavy cream.
Can I make this vegetarian?
Easy! Replace the bacon with 1 cup cooked tempeh crumbles or 1 cup vegan bacon bits. For extra umami, add 1 tablespoon soy sauce to the egg mixture. Swap cheddar for vegan sharp cheddar (like Violife) and use 1 cup nutritional yeast instead of half the milk for a cheesy flavor without dairy. The texture stays identical!
What's the secret to perfect runny yolks?
Three things: room temperature eggs, low-and-slow cooking, and not overmixing. Whisk just until combined (about 1 minute), then fold in the hash browns gently. Cook until the edges are set but the center still wobbles slightly—160°F internal temp is ideal. Serve immediately for maximum gooeyness, or cover tightly with foil to hold heat while you plate.
