Instructions
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Grease a 9×9-inch baking dish with cooking spray or butter.
Step 2: Brown the Beef
Heat a large skillet over medium-high heat.
Add the ground beef and cook until it begins to brown, breaking it into crumbles as it cooks.
Step 3: Cook the Vegetables
Add the chopped onion and bell peppers to the skillet.
Cook for 5–6 minutes, stirring occasionally, until the vegetables begin to soften and the beef is fully browned.
Step 4: Season
Add:
- Minced garlic
- Seasoned salt
Cook for another 30 seconds until fragrant.
Drain any excess grease thoroughly.
Step 5: Assemble the Casserole
Spread the beef and vegetable mixture evenly into the prepared baking dish.
Arrange the provolone cheese slices evenly over the top.
Step 6: Prepare the Egg Mixture
In a medium bowl whisk together:
- Eggs
- Heavy whipping cream
- Worcestershire sauce
Mix until smooth.
Slowly pour the mixture evenly over the casserole.
Step 7: Bake
Bake uncovered for 35–40 minutes, or until:
- The eggs are fully set
- The cheese is melted and golden
- The center no longer jiggles
Step 8: Cool and Serve
Allow the casserole to rest for 5–10 minutes before slicing.
Garnish with chopped parsley if desired and serve warm.
Tips for Success
- Drain the beef thoroughly to avoid a greasy casserole.
- Use freshly sliced provolone for the best melt.
- Let the casserole rest before cutting for clean slices.
- Don’t overcook the vegetables—they’ll continue cooking in the oven.

Frequently Asked Questions
Can I use steak instead of ground beef?

Is this keto-friendly?
Yes. With no bread or pasta, it’s naturally low in carbohydrates and ideal for keto and low-carb diets.
Can I use another cheese?

Excess grease can prevent the egg mixture from setting properly and make the casserole watery.
