🧑🍳 About This Recipe
I whipped this up one night when I had ground beef, leftover cheese, and zero motivation for dishes. What came out of the oven surprised even me — bubbly, cheesy, and so satisfying it’s become a weekly staple. This dish checks every box: easy, comforting, and endlessly adaptable. Think of it like crustless pizza meets a baked frittata!
📸 Step-by-Step Guide
1. Cook the Beef
Sauté the beef with garlic and onions until browned. Break it up into small crumbles.
Tip: Drain excess fat to avoid a greasy casserole.
2. Mix the Egg Base
Whisk together eggs and cream — this makes the casserole fluffy and holds everything together.
3. Layer & Top
In a greased baking dish:
- Add the beef mixture
- Pour over the egg base
- Top with diced peppers and shredded cheese
Tip: Press down gently with a spatula so the egg base spreads evenly.
4. Bake Until Golden
Bake at 375°F for 25–30 minutes. The top should be bubbly and golden.
🧂 Ingredient & Substitution Tips
Key Ingredients
- Ground beef: 85–90% lean is best.
- Cheese: A mix of mozzarella and cheddar gives that classic melt + flavor combo.
- Heavy cream: Adds richness and helps bind the eggs.
- Eggs: The structure of the casserole — don’t skip them!
- Green bell pepper: Adds crunch and color.
Substitutions
- Meat: Ground turkey or sausage also work.
- Cheese: Try Monterey Jack, pepper jack, or provolone.
- Cream: Use half-and-half or unsweetened almond milk for a lighter version.
- Veggies: Add mushrooms, spinach, or even jalapeños for kick.
Equipment Notes
- Don’t have a square baking dish? Use a 9×13″ pan for thinner slices — just reduce baking time by ~5 minutes.
- No whisk? A fork works fine to mix eggs and cream.
