This casserole has been my go-to for busy mornings and lazy Sundays alike. I first put this together when our weekday routine demanded something I could assemble the night before and simply pop into the oven as we got ready for the day. The combination of steamable frozen broccoli, smoky bacon, creamy eggs, and mild cheddar creates a comforting, savory bite that feels indulgent while still being low in carbs. It’s the kind of dish that fills the kitchen with a warm, inviting aroma and gets everyone asking what’s for breakfast.

What makes this version special is how forgiving and adaptable it is. I rely on a 12-ounce bag of steamable broccoli because it keeps the texture consistent and saves time. The custardy egg mixture, enriched with heavy cream and seasoned with a touch of onion and garlic powder, sets around the vegetables and bacon into a sliceable, satisfying breakfast that reheats beautifully. Over the years I’ve brought this casserole to potlucks, prepped it for meal prep weeks, and tucked a pan into the fridge for holiday mornings — it always disappears fast.

Ingredients

• Steamable frozen broccoli (1 12-ounce bag): I favor the steamable bags for consistent texture and convenience. The florets release just enough moisture when steaming in-bag, so they remain bright and tender when combined with the egg mixture.
• Shredded mild cheddar (1 cup): Choose freshly shredded cheddar if possible for melting quality — pre-shredded can contain anti-caking agents that affect creaminess. Mild cheddar keeps the flavor balanced and kid-friendly.
• Bacon (6 slices): Thick-cut or regular both work; cook until crisp to provide texture contrast. Reserve the rendered fat for greasing the dish if you like the added flavor.
• Large eggs (4): Room-temperature eggs give the best, even custard. They bind the casserole and create a tender, sliceable texture.
• Heavy cream (1/3 cup): Adds richness and helps the eggs set into a creamy custard. For a lighter option, use half-and-half, though the texture will be slightly less rich.
• Onion powder (1/2 teaspoon) and garlic powder (1/2 teaspoon): Simple seasonings that add depth without overpowering the other ingredients. Adjust to taste.
• Salt (1/4 teaspoon) and black pepper (1/4 teaspoon): Basic seasoning — keep in mind bacon can be salty, so taste before adding more.

Instructions

Step 1 — Preheat and prepare: Preheat the oven to 350 degrees Fahrenheit. Lightly grease an 8x8-inch baking dish with butter or a little of the reserved bacon fat to prevent sticking. If using frozen broccoli, steam it according to package instructions and let it cool slightly so it doesn’t water down the egg mixture. Step 2 — Cook the bacon: In a skillet over medium heat, cook 6 slices of bacon until crisp, about 8–10 minutes depending on thickness. Transfer to a paper towel-lined plate and chop or crumble once cooled. Reserve a teaspoon of bacon fat for flavoring the dish if desired. Step 3 — Whisk the custard: In a medium bowl, whisk together 4 large eggs and 1/3 cup heavy cream until smooth and slightly frothy. Stir in 1/2 teaspoon onion powder, 1/2 teaspoon garlic powder, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. The whisking incorporates air that helps create a light, tender set. Step 4 — Assemble the casserole: Spread the steamed broccoli evenly in the prepared baking dish. Scatter the crumbled bacon over the broccoli, then sprinkle 1 cup shredded mild cheddar evenly across the top. Pour the egg and cream mixture over everything, pressing gently so the liquid settles around the vegetables. Step 5 — Bake until set: Bake in the preheated oven for 16–20 minutes, or until the center is just set and the edges are lightly golden. A toothpick inserted into the center should come out with just a few moist crumbs; avoid overbaking to keep the casserole tender. Step 6 — Rest and serve: Let the casserole rest for 5 minutes after removing from the oven to make slicing easier. Serve warm, garnished with a sprinkle of extra cheddar or a few fresh herbs if desired.

Storage Tips

Cool the casserole to room temperature for no more than two hours before refrigerating. Store in an airtight container or cover the baking dish tightly with foil or plastic wrap. Refrigerated portions will keep for up to four days. For longer storage, slice into individual portions, wrap each in plastic wrap and aluminum foil, and freeze; they will keep up to three months. Reheat from frozen in a 350 degree Fahrenheit oven until warm throughout, about 20–30 minutes, or thaw overnight in the refrigerator for quicker reheating.

Ingredient Substitutions

If you don’t have steamable broccoli, use fresh broccoli florets (about 2 cups), briefly blanching them for 1–2 minutes to remove raw harshness. Swap mild cheddar for Monterey Jack, Colby, or a sharp cheddar for bolder flavor; use 1 cup of any shredded melting cheese. For dairy-free adaptations, omit the cheese and substitute heavy cream with full-fat coconut milk, noting the flavor shift. To make it vegetarian, replace bacon with smoked tempeh or roasted mushrooms for a smoky bite.

Serving Suggestions

Serve warm slices with a side of sliced avocado or a light mixed-green salad dressed with lemon and olive oil. For a heartier brunch, pair with a bowl of fresh fruit or a dollop of sour cream and chopped chives atop each slice. Garnish with sliced green onions or a sprinkle of red pepper flakes for a touch of heat. This casserole also makes a great base for breakfast plate assemblies at weekend gatherings.

Cultural Background

This type of baked egg-and-vegetable dish draws inspiration from strata and frittata traditions across many cuisines, where eggs are combined with bread, vegetables, or meats and baked until set. In American home cooking, layered breakfast bakes became popular for their ease of serving and make-ahead practicality, especially for holidays and potlucks. This recipe translates that concept into a low-carb, ketogenic-friendly format by replacing bread with vegetables and relying on cream and cheese for richness.

Seasonal Adaptations

In spring and summer, substitute tender asparagus or sautéed spinach for broccoli and add fresh herbs like dill or basil. In fall and winter, fold in roasted butternut squash or caramelized onions for deeper flavors — note that squash increases the carbohydrate count. For holiday weekends, top with crumbled cooked sausage or stir in chopped roasted peppers to create a festive variation.

Meal Prep Tips

Assemble the casserole the night before and leave it covered in the refrigerator; bake in the morning for a freshly baked breakfast with minimal morning effort. Alternatively, bake ahead, cool, and portion into containers for grab-and-go breakfasts. To maintain moisture when reheating, add a few drops of water or a thin smear of butter on top before warming in the oven or microwave.

Give this a try on a busy morning or for a relaxed weekend brunch — it’s dependable, delicious, and easily personalized. I hope it becomes a staple on your table as it has on mine.
