Ingredients
Method
- Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil.
- Blanch the broccoli: Bring a pot of salted water to a boil. Add broccoli and cook for 2 minutes until bright green and just tender. Drain well and set aside. If using frozen, thaw and pat dry to avoid excess water.
- Brown the beef: In a large skillet over medium-high heat, cook the ground beef until browned and crumbly. Season with salt, pepper, Italian seasoning, and onion powder. Drain excess fat if needed.
- Add garlic: Reduce heat to medium. Add minced garlic to the skillet and cook for 30–45 seconds until fragrant. Remove the beef mixture to a large bowl.
- Make the Alfredo sauce: In the same skillet, melt butter over medium heat. Stir in heavy cream and bring to a gentle simmer. Add cream cheese and whisk until smooth. Stir in Parmesan until melted and the sauce is thick and glossy. Season with salt, pepper, and red pepper flakes if using.
- Combine: Add the blanched broccoli to the bowl with the beef. Pour the Alfredo sauce over the top and toss until everything is evenly coated.
- Assemble the bake: Transfer the mixture to the prepared baking dish. Sprinkle mozzarella evenly over the top. Add a little extra Parmesan if you like a more pronounced cheesy crust.
- Bake: Place in the oven and bake for 18–22 minutes, until the cheese is melted and bubbling. For a golden top, broil for 1–2 minutes at the end, watching closely.
- Rest and serve: Let the bake sit for 5 minutes to set. Taste and finish with a pinch of salt and pepper if needed. Serve warm.

Keeping It Fresh
- Refrigerate: Store leftovers in an airtight container for up to 4 days.
- Freeze: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge.
- Reheat: Warm in a 325°F (165°C) oven for 12–15 minutes or microwave in short bursts, stirring halfway.
Add a splash of cream if it looks dry.
- Meal prep tip: Assemble ahead and refrigerate unbaked for up to 24 hours. Add 5–8 minutes to the bake time if going straight from the fridge.

- One-dish convenience: Fewer pans, less cleanup, easy assembly.
- Kid-approved: Familiar flavors, mild seasoning, and cheesy goodness.

What Not to Do
- Don’t skip draining or drying: Excess moisture from beef or broccoli will make the bake watery.
- Don’t overcook the broccoli: Mushy florets lose texture. Keep them crisp-tender before baking.
- Don’t let the sauce boil hard: A gentle simmer keeps the Alfredo smooth and prevents separating.
- Don’t overload with extra cheese in the sauce: Too much can make it grainy.
Use the amounts listed and add more on top if you want.
Alternatives
- Protein swaps: Ground turkey, chicken, sausage, or a mix of beef and Italian sausage all work well.
- Veggie swaps: Cauliflower, zucchini (patted dry), or spinach can replace or join the broccoli.
- Dairy-free option: Use unsweetened coconut cream and a dairy-free cream cheese and Parmesan-style alternative. Flavor with extra garlic and nutritional yeast.
- Cheese variations: Try provolone, fontina, or a cheddar–Parmesan blend for a different flavor profile.
- Added flavor boosts: A squeeze of lemon, a pinch of nutmeg in the sauce, or a sprinkle of smoked paprika on top.
FAQ
Is this casserole truly keto-friendly?
Yes. It uses low-carb vegetables and a high-fat, moderate-protein sauce.
There’s no pasta or flour. Check labels on cream cheese and Parmesan to ensure no hidden carbs.
Can I make it ahead?
Absolutely. Assemble it, cover, and refrigerate up to 24 hours.
Bake when ready, adding a few extra minutes to account for the cold dish.
How do I prevent a watery bake?
Drain the cooked beef, blanch broccoli briefly and dry it well, and avoid covering the dish while baking. If using frozen broccoli, thaw and pat very dry.
Can I use jarred Alfredo sauce?
You can, but read the label. Many jars have starches or sugars.
The homemade sauce here is quick and reliably low-carb with better flavor.
What side dishes go well with this?
A simple green salad with olive oil and vinegar, roasted asparagus, or sautéed zucchini are great. Keep sides light and fresh to balance the richness.
Can I make it spicier?
Yes. Add extra red pepper flakes, a bit of cayenne, or use spicy Italian sausage for part of the meat.
How can I reduce calories without adding carbs?
Use 90% lean ground beef or ground turkey, reduce the mozzarella slightly, and keep portions measured.
The dish will still taste rich thanks to Parmesan and cream.
What pan size should I use?
A 9×13-inch baking dish works best. If you use a smaller dish, increase bake time a bit and watch for bubbling edges and a melted top.
Can I add bacon?
Yes, and it’s delicious. Cook crispy bacon, crumble it, and fold it in with the beef and broccoli or sprinkle it over the top before baking.
How do I keep the sauce silky?
Simmer gently, whisk in cream cheese until smooth before adding Parmesan, and avoid high heat.
If it thickens too much, whisk in a splash of cream.
