High-Protein Taco Casserole
Seasoned beef, melted cheese, fresh toppings – 30 minutes, one dish
This is a taco casserole, not a chip bake. Ground beef, sugar-free taco seasoning, and a cheese blanket go in a glass dish, then diced tomato, black olives, and green onion hit the top after the melt, like the pan in the photo. Thirty minutes. No tortillas, no chips.
Six servings. Drain the beef or the dish goes greasy.

Key element – drain the beef, then add fresh toppings after the melt
Wet beef makes a greasy casserole. Drain it well, then bind with a little cream cheese so the squares hold. Cheese goes in the oven. Tomato, olives, and green onion go on after, so they stay bright like the photo instead of steaming into mush.
Ingredients
Casserole (6 servings)
- 2 lb (900g) lean ground beef (90/10 or 93/7)
- 1 small onion, diced
- 3 garlic cloves, minced
- 2 Tbsp chili powder
- 1 tsp cumin
- 1 tsp smoked paprika
- 1 tsp salt + 1/2 tsp black pepper
- 1/2 tsp oregano
- 4 oz cream cheese, cubed
- 1/2 cup salsa (no sugar)
- 2 cups shredded cheddar or Mexican blend
Finish (like the photo)
- 1 cup diced tomato, patted dry
- 1/3 cup sliced black olives
- 1/4 cup sliced green onion
Swaps
- Turkey: Use 2 lb ground turkey. Add 1 Tbsp oil so it does not dry out.
- Cauliflower rice: Stir 2 cups cooked, squeezed-dry cauliflower into the beef if you want more bulk.
- No cream cheese: Use 1/2 cup thick Greek yogurt off the heat.
- Hot: Add 1 diced jalapeno with the onion.
Instructions
| 1 | Heat the oven. Heat oven to 375 F (190 C). Lightly oil a glass 9×13 or 8×11 dish. |
| 2 | Brown. Cook beef and onion in a skillet on medium-high 7 to 8 minutes, breaking it up, until no pink remains. Drain the fat. Stir in garlic and spices 30 seconds. |
| 3 | Bind. Drop the heat. Stir in cream cheese and salsa until the mix looks creamy, not watery. |
| 4 | Cheese and bake. Spread in the dish. Cover with cheddar. Bake 15 to 18 minutes until the cheese is melted and bubbling at the edges, like the photo. |
| 5 | Top and rest. Scatter tomato, olives, and green onion on the hot cheese. Rest 5 minutes. Cut into 6 squares. |
Pro tips
- Drain the beef well. Extra fat pools under the cheese.
- Pat the tomato dry so the top does not go watery.
- Fresh toppings after the bake. They stay bright like the photo.
- Do not bake past a melt. Dry cheese turns rubbery.
- Rest 5 minutes so the squares cut clean.
