Ingredients for betty crocker egg casserole
Sixteen simple ingredients transform into Betty Crocker's legendary herb-crusted egg casserole.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 12 whole | Room temperature preferred |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium or sharp variety |
| Milk 🥛 | 1 cup | Whole milk for creaminess |
| Butter 🧈 | ½ cup | Unsalted, melted |
| Green Bell Pepper 🧅 | 1 medium | Diced, seeds removed |
| Red Onion 🧅 | 1 medium | Diced, white parts only |
| Fresh Spinach 🌿 | 4 cups | Chopped, loosely packed |
| Dried Parsley 🌿 | 2 tbsp | Or 1 tbsp fresh chopped |
| Dried Dill 🌿 | 1 tbsp | Or 1 tsp fresh chopped |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| All-Purpose Flour 🌾 | ½ cup | For herb crust |
| Breadcrumbs 🍞 | ½ cup | Panko for extra crispiness |
| Olive Oil 🫒 | 1 tbsp | For greasing pan |
The cheese is non-negotiable here—sharp cheddar melts best, but monterey jack works too. Grab the pre-shredded kind from the store for convenience, but if you're feeling fancy, grate it yourself for that perfect melt. The spinach should be fresh—wilted or frozen won't work. For the herbs, dried is fine, but fresh parsley and dill add a brighter flavor. If you're short on time, Trader Joe's has pre-chopped veggie mixes that save prep work. The eggs? Room temperature beats straight-from-the-fridge for even baking.
No bell pepper? Zucchini or mushrooms work in a pinch—just adjust the amount since they release more moisture. Swapping cheddar for mozzarella makes it milder, but lose the crispy crust. For a lighter version, reduce the cheese by half and add extra spinach. The herb crust can be made ahead—just mix the flour, breadcrumbs, and herbs, then store in a sealed container. If you're using panko, toast it first in a dry pan for 2-3 minutes to boost the flavor. The milk can be skim or whole, but whole gives the best creamy texture.
This casserole reheats beautifully—30 seconds in the microwave or until warmed through in the oven. Store leftovers covered in the fridge for up to 5 days. For meal prep, portion into individual containers before baking for easy grab-and-go breakfasts. The herb crust stays crispy for 2 days if kept dry in an airtight container. Freeze baked portions for up to 2 months—just thaw overnight in the fridge before reheating. The aroma alone will wake up your whole household.
Why You'll Love This Recipe
- One-Bowl Magic: I swear by this recipe when I’m too tired to wash dishes. Just toss eggs, milk, cheese, and chopped bell pepper into one bowl, stir, then pour into a buttered pan—no extra mixing or fussing. The butter melts into the milk while it bakes, creating that creamy, golden crust without extra effort.
- Cheese Pull Factor: That moment when the top turns golden and the cheddar stretches like melted butter? Yes. The sharpness of the cheese cuts through the richness of the eggs, and the bell pepper adds just enough brightness to keep it from being heavy. Honestly, I’ve seen grown adults reach for seconds over this.
- Lunchbox Hero: Between us, this is my go-to for meal prep. Bake a big batch on Sunday, slice it up, and you’ve got grab-and-go breakfasts or lunches all week. The cheese holds up surprisingly well, and the eggs stay tender—no sad, rubbery leftovers here. (Yes, even on a Tuesday night.)
- Pantry Staple Power: I keep eggs, cheese, and milk on hand just for this. It’s one of those recipes that turns basic ingredients into something special without breaking the bank. Plus, if you’ve got extra bell pepper lying around, toss it in—no waste, all flavor. Budget-friendly doesn’t mean boring.
Step-by-step instructions for herb-crusted one-pan breakfast brilliance
Here's how to assemble this crowd-pleasing breakfast casserole with a golden crust and creamy interior.
Prepare the Vegetable and Cheese Mixture
Preheat your oven to 350°F while you prepare the base. In a large bowl, combine the diced green bell pepper and red onion. Add the 4 cups fresh spinach and toss gently until just wilted. This keeps the vegetables tender without turning mushy during baking.
Next, fold in 2 cups shredded cheddar cheese, 1.5 teaspoons salt, and 0.5 teaspoon black pepper. The cheese will begin to soften slightly from the room-temperature vegetables, creating a smooth, creamy texture when baked. Set this mixture aside while you prepare the egg base.
Create the Egg and Milk Base
In a separate large bowl, whisk together the 12 whole large eggs and 1 cup milk until fully combined. The eggs should be at room temperature for even cooking—this prevents them from curdling in the oven. Add 0.5 cup melted butter and whisk again until smooth and emulsified.
Here's the thing—this step sets the foundation for your casserole. If you whisk vigorously, you'll incorporate air that helps create a lighter texture. Pour the egg mixture over the vegetable-cheese mixture and stir gently to distribute evenly. Don't overmix; you want just enough blending to combine without breaking up the spinach too much.
Assemble the Herb-Crusted Topping
In a medium bowl, combine 0.5 cup all-purpose flour, 0.5 cup breadcrumbs, 2 tablespoons dried parsley, 1 tablespoon dried dill, and 1 tablespoon olive oil. Mix with your fingers until the breadcrumbs are evenly coated and the mixture resembles coarse sand.
This herb crust is what gives the casserole its signature golden finish. The breadcrumbs provide texture while the herbs add fresh flavor. If your breadcrumbs are too dry, add a splash of milk to help them bind together. Spread this mixture evenly over the top of the egg mixture in your baking dish.
Bake to Golden Perfection
Transfer the baking dish to the preheated 350°F oven and bake for 40-45 minutes. The casserole is done when the top is golden brown and a knife inserted near the center comes out clean. The internal temperature should reach 160°F—this ensures the eggs are fully set while remaining creamy.
I always check for doneness at the 35-minute mark because ovens vary. If the top browns too quickly, tent it loosely with foil to prevent over-browning while the center finishes cooking. Let it rest for 5-10 minutes before serving—this allows the juices to redistribute and prevents a runny center when you cut into it.
Serve Warm with Fresh Garnishes
Cut into 6 equal portions and serve immediately. The top should be crispy and golden, while the interior remains creamy with tender vegetables throughout. For extra presentation, sprinkle with fresh chopped parsley or a dash of hot sauce if you like a bit of kick.
This casserole reheats beautifully for breakfast the next day—just cover and refrigerate, then warm in the oven at 325°F for 15-20 minutes. The herb crust will crisp up again, and the eggs will stay creamy rather than rubbery. Perfect for meal prep on busy mornings!
Pro Tips For Making Betty Crocker Egg Casserole
- Preheat Pan, Not Just Oven: I learned this the hard way—skipping a hot pan for the butter and peppers leads to sad, steamed veggies instead of crisp edges. Get that skillet smoking over medium-high before adding butter, then toss in the bell pepper strips. You want them to sizzle, not sigh.
- Dry Cheese Like Your Life Depends On It: Wet cheese clumps and sinks, so grab a clean kitchen towel and press it against the shredded cheddar in the bowl. Work it like you’re wringing out a sponge—this removes excess moisture and guarantees a golden crust, not a soggy mess. (Yes, even if you’re impatient like me.)
- Whisk Eggs Until They’re Mean: Over-beaten eggs turn rubbery, but under-whisked ones separate like a bad relationship. Beat the eggs and milk until the yolks and whites are uniform—no streaks, no lumps—then fold in the cheese mixture. Stop when it’s just combined, not when your arm gives out.
- Layer Cheese Like a Lasagna: Don’t just dump it all on top—sprinkle half the cheddar between the egg mixture and the remaining half on the surface. The top layer crisps up faster, while the hidden layer keeps the whole thing from turning into a cheesy brick. (Your future self will thank you.)
Perfect pairings for these flavors
Classic Side Pairings
Start with a simple fruit salad—mix 1 cup diced pineapple, 1 cup seedless grapes, and 1 cup blueberries with a squeeze of lemon juice. The sweetness cuts through the savory richness of the casserole beautifully. For a heartier option, serve with crusty sourdough toast and a dollop of whipped butter—perfect for soaking up any extra egg mixture. 🍓
Beverage Harmony
An iced black coffee with a splash of vanilla syrup balances the dish's richness while keeping mornings energized. For a non-coffee option, try sparkling apple cider—the effervescence cleanses the palate between bites. If you prefer tea, a hot English breakfast tea with honey adds warmth and depth to the meal.
Sweet Contrasts
Add a cinnamon-sugar toast by brushing toasted bread with melted butter, sprinkling with 1 tbsp cinnamon and 1 tbsp sugar, then toasting until golden. The warmth of cinnamon complements the savory herbs in the casserole. For a lighter touch, serve with Greek yogurt drizzled with honey and a sprinkle of granola.
Breakfast Beverage Upgrades
Elevate your morning with a turmeric latte—steep 1 tsp turmeric in hot milk with a pinch of black pepper and a dash of cinnamon. The anti-inflammatory properties pair wonderfully with the casserole's cheesy goodness. For a classic touch, orange juice with a pinch of salt enhances the flavors and adds a refreshing zing. 🍊
Herb-Inspired Garnishes
Fresh chopped chives or dill sprinkled on top add a bright, herby finish that ties back to the crust. A drizzle of hot honey (mix 1 tbsp honey with a pinch of cayenne) adds a subtle kick. For a smoky note, serve with crumbled bacon or a side of avocado slices—the creaminess of the avocado balances the crust's crispiness.
Make-Ahead Pairing Tips
Prepare the casserole the night before and store it covered in the fridge. Pair with pre-cut veggie sticks (carrots, celery, bell peppers) and a hummus dip for a quick, no-cook side. For a full brunch spread, assemble a mini charcuterie board** with cured meats, olives, and marinated artichokes—great for serving alongside the casserole when entertaining. 🧀

Frequently asked questions
Can I make this egg casserole without a crust?
The herb crust adds that signature golden crunch, but you can absolutely skip it! Simply bake the egg mixture uncovered for 35-40 minutes at 350°F until set. For extra flavor, sprinkle with extra cheese or herbs before baking. The texture will be softer but still delicious.
How do I adjust this recipe for fewer servings?
This recipe makes 6 servings, but you can easily halve it for 3 servings. Use 6 eggs, 1 cup cheese, and ½ cup milk. The baking time remains the same (40-45 minutes) since the depth of the dish stays similar. A 9-inch pie dish works perfectly for smaller batches.
My casserole came out rubbery—what went wrong?
Rubbery eggs usually mean overcooking or eggs that were too cold. First, ensure your eggs are at room temperature before whisking. Second, check doneness with a 160°F internal temp—never bake beyond 45 minutes. If you overbake, try reheating gently with a splash of milk to restore creaminess.
Can I add meat like ham or sausage?
Cook ½ cup diced ham or ½ lb crumbled sausage until fully cooked, then fold into the veggie-cheese layer. For sausage, drain excess fat first. The meat adds protein and heartiness—great for a dinner-style casserole. Just reduce the baking time by 5 minutes since meat cooks faster than eggs.
How long will leftovers keep in the fridge?
Store leftovers in an airtight container for up to 5 days. Reheat covered in the oven at 325°F for 15-20 minutes to restore crispiness. Avoid microwaving—it makes the crust soggy. For best texture, reheat individual portions rather than the whole dish.
