What You Need: Ingredients for a High Protein Beef and Broccoli Casserole

Here's the beauty of this dish — no specialty store required. Everything comes from a standard grocery run.

The Protein-Packed Base

Ingredient	Amount	Why It's Here
Lean ground beef (90/10)	1.5 lbs	Primary protein source
Eggs	3 large	Binds the casserole + adds protein
Plain Greek yogurt	½ cup	Creamy texture + extra protein boost
Shredded cheddar cheese	1 cup	Flavor, fat, and that golden top

The Veggie Layer

Ingredient	Amount	Notes
Fresh broccoli florets	4 cups	Lightly steamed or raw
Garlic cloves, minced	3	Do yourself a favor — use fresh
Yellow onion, diced	1 medium	Flavor foundation

The Flavor Builders

• 2 tbsp soy sauce (or coconut aminos for gluten-free)
• 1 tsp sesame oil
• 1 tsp garlic powder
• Salt and black pepper to taste
• Red pepper flakes (optional, for a little kick)

Fair warning: the sesame oil is small but mighty. Don't skip it — it's what gives this casserole that classic beef and broccoli flavor that makes people ask for the recipe.

How to Make a High Protein Beef and Broccoli Casserole (Step-by-Step)

This is genuinely straightforward. No judgment here if you need to read the steps twice — but you won't.

Step 1: Preheat and Prep (5 minutes)

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 baking dish. If using fresh broccoli, steam it for 3–4 minutes until just tender — you want it bright green, not mushy.

Step 2: Brown the Beef (8–10 minutes)

In a large skillet over medium-high heat, cook the ground beef with diced onion and garlic until no pink remains. Drain any excess fat. Stir in soy sauce, sesame oil, garlic powder, salt, pepper, and red pepper flakes. Pull it off the heat.

Step 3: Build the Casserole

In a large bowl, whisk together eggs and Greek yogurt until smooth. Add the cooked beef mixture and broccoli florets. Stir to combine, then pour everything into your prepared baking dish. Spread evenly and top with shredded cheddar.

Step 4: Bake to Golden Perfection (25–30 minutes)

Bake uncovered at 375°F for 25–30 minutes, until the cheese is bubbly and golden and the center is set. Let it rest for 5 minutes before serving — trust me on this one, it slices so much better.

Nutrition Snapshot: The Protein Numbers

Here's roughly what one serving (⅙ of the casserole) delivers:

Nutrient	Approximate Amount
Calories	380–420 kcal
Protein	38–42g
Carbohydrates	8–10g

Crowd-pleaser alert: these macros make this dish a serious win for anyone tracking protein, eating low-carb, or just trying to feel full without overeating.

Tips, Swaps & Meal Prep Magic

Make it work for your life:

• 🔄 Swap ground beef for ground turkey or bison to change the fat profile
• 🧀 Go dairy-free with a plant-based cheese and coconut yogurt
• 🌾 Keep it gluten-free by using coconut aminos instead of soy sauce
• 🥦 Frozen broccoli works — just thaw and pat dry first to avoid a watery casserole
