Why I Love This Recipe
Taco night is always good, but sometimes I want all those flavors without setting out a dozen bowls of toppings. That’s how casseroles like this became part of my dinner rotation.
This one keeps the flavors people expect from tacos but turns them into one warm, cheesy dish. Lean beef and black beans make it filling, while cottage cheese adds extra protein without making the casserole feel heavy.
I also like that the ingredients are easy to find. There’s no complicated sauce or long prep. Once the beef is cooked, everything comes together quickly.
- High in protein: Lean beef, black beans, cottage cheese, and shredded cheese all add protein.
- Easy taco flavor: Taco seasoning and salsa do most of the flavor work.
- Simple ingredients: Everything is easy to find at a regular grocery store.
- Great texture: You get tender beef, creamy filling, beans, corn, soft tortillas, and melted cheese.
- Good for leftovers: Individual portions reheat well for quick lunches and dinners.
What You’ll Need
- 1 1/2 pounds 93% lean ground beef
- 1 tablespoon olive oil
- 1 medium onion, diced
- 3 cloves garlic, minced
- 2 tablespoons taco seasoning
- 1/2 cup water
- 1 (15-ounce) can black beans, drained and rinsed
- 1 cup corn, drained if canned or thawed if frozen
- 1 1/2 cups chunky salsa
- 1 cup low-fat cottage cheese
- 1/2 cup plain nonfat Greek yogurt
- 8 small corn tortillas, cut into bite-sized pieces
- 1 1/2 cups shredded reduced-fat Mexican-blend cheese, divided
- 2 tablespoons chopped fresh cilantro, for serving
Pro Tips
- Use lean beef. A 93% lean ground beef gives you plenty of flavor without leaving a lot of grease in the casserole.
- Drain the beans well. Extra water from the beans can make the filling loose.
- Use chunky salsa. It adds flavor and moisture without making the casserole too watery.
- Don’t skip the cottage cheese blend. Blending cottage cheese with Greek yogurt gives you a smooth, creamy filling with extra protein.
- Rest before serving. Five to 10 minutes gives the casserole time to settle and makes it easier to scoop.
Tools You’ll Need
- 9×13-inch baking dish
- Large skillet
- Large mixing bowl
- Blender or food processor
- Cutting board
- Sharp knife
- Wooden spoon
- Rubber spatula
- Measuring cups
- Measuring spoons
Substitutions and Variations
Ground turkey: Use 93% lean ground turkey instead of beef for a lighter variation.
Ground chicken: Ground chicken also works. Since it is mild, make sure you use the full amount of taco seasoning.
Pinto beans: Swap the black beans for drained and rinsed pinto beans.
Corn tortillas: Small flour tortillas work, but they create a softer casserole and change the nutrition.
Cheese: Cheddar, Monterey Jack, or pepper Jack can replace the Mexican-blend cheese.
Salsa: Mild, medium, or hot salsa all work. Choose the heat level you prefer.
More heat: Add diced jalapeño or a pinch of cayenne to the beef mixture.
Make Ahead Tips
You can prepare the beef mixture up to 2 days ahead. Let it cool, then refrigerate it in an airtight container.
The creamy cottage cheese mixture can also be blended a day ahead and stored in the refrigerator.
For the best tortilla texture, I prefer assembling the full casserole shortly before baking. You can still assemble it several hours ahead if needed. Cover and refrigerate, then add about 5 extra minutes to the baking time if it goes into the oven cold.
How to Make High Protein Taco Casserole
Step 1: Prep the Oven and Ingredients
Preheat the oven to 375°F (190°C).
Dice 1 medium onion, mince 3 cloves garlic, and cut 8 small corn tortillas into bite-sized pieces. Drain and rinse 1 (15-ounce) can black beans. Prepare 1 cup corn by draining canned corn or thawing frozen corn.
Step 2: Cook the Onion and Beef
Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the 1 diced medium onion and cook for about 2 minutes.
Add 1 1/2 pounds 93% lean ground beef. Cook for 5 to 7 minutes, breaking the beef into small crumbles with a wooden spoon, until browned and cooked through.
Drain excess grease if needed.
Step 3: Season the Beef
Reduce the heat to medium. Add the 3 minced garlic cloves and 2 tablespoons taco seasoning to the cooked beef and onion. Stir for about 30 seconds.
Pour in 1/2 cup water. Cook for 2 to 3 minutes, stirring occasionally, until the water has reduced and the taco-seasoned beef is moist but not watery.
Remove the skillet from the heat.
Step 4: Make the Creamy High-Protein Mixture
Add 1 cup low-fat cottage cheese and 1/2 cup plain nonfat Greek yogurt to a blender or food processor.
Blend until completely smooth and creamy. There should be no visible cottage cheese curds or lumps.
Step 5: Combine the Taco Filling
In a large mixing bowl, add the seasoned beef mixture from Step 3.
Add the drained and rinsed 15-ounce can black beans, 1 cup corn, 1 1/2 cups chunky salsa, the blended cottage cheese and Greek yogurt mixture from Step 4, the 8 corn tortillas cut into bite-sized pieces, and 3/4 cup of the 1 1/2 cups shredded reduced-fat Mexican-blend cheese.
Fold everything together until evenly combined.
Step 6: Assemble the Casserole
Spread the taco mixture evenly into a 9×13-inch baking dish.
Sprinkle the remaining 3/4 cup shredded reduced-fat Mexican-blend cheese evenly over the top.
Step 7: Bake
Bake uncovered at 375°F (190°C) for 20 to 25 minutes, until the casserole is hot throughout and the remaining 3/4 cup Mexican-blend cheese has completely melted.
For a lightly browned top, broil for 1 to 2 minutes at the end. Watch closely.
Step 8: Rest, Garnish, and Serve
Let the casserole rest for 5 to 10 minutes. Spoon portions into serving bowls and finish with 2 tablespoons chopped fresh cilantro, divided over the servings. Serve warm.
Why This Recipe Works (Quick Science)
Lean beef gives the casserole structure. Browning the beef first removes excess moisture and creates deeper savory flavor.
Reducing the water matters. The water helps taco seasoning coat the beef, but cooking it down keeps the casserole from becoming soggy.
Blended cottage cheese makes a smooth sauce. Blending breaks down the curds, so you get a creamy texture instead of noticeable cottage cheese pieces.
Greek yogurt adds body. It helps make the filling creamy while adding more protein.
Corn tortillas absorb flavor. As they bake, the tortilla pieces soften and absorb some of the salsa and seasoned beef juices. This helps bind the casserole together.
Resting sets the filling. The casserole is softer straight from the oven. Giving it 5 to 10 minutes to rest makes it easier to scoop.
Common Mistakes
Leaving too much grease in the skillet: If your beef releases a lot of fat, drain it before adding the seasonings.
Not reducing the water: The seasoned beef should be moist, not swimming in liquid.
Using very watery salsa: A thick, chunky salsa works better in a casserole.
Not draining the beans: Rinse them, then let the excess water drain before adding them.
Leaving cottage cheese lumpy: Blend it with the Greek yogurt until completely smooth if you want a creamy, even texture.
Overbaking the casserole: The beef is already cooked. The oven only needs to heat everything through, soften the tortillas, and melt the cheese.

What to Serve With
This casserole is already a filling meal, so simple sides work well. Try a crisp green salad, roasted zucchini, grilled peppers, sautéed vegetables, or a fresh tomato and avocado salad.
You can also serve it with shredded lettuce, diced tomatoes, avocado, lime wedges, extra salsa, Greek yogurt, or pickled jalapeños so everyone can add their favorite taco toppings.
Leftovers and Storage
Let the casserole cool before storing it. Keep leftovers in an airtight container in the refrigerator for up to 3 to 4 days.
Reheat individual servings in the microwave until hot throughout. For several portions, cover them in an oven-safe dish and warm at 350°F until heated through.
You can also freeze individual portions for up to 2 months. Thaw them overnight in the refrigerator before reheating. The tortillas will become a little softer after freezing, but the flavor will still be good.
FAQ
Can I use ground turkey instead of beef?
Yes. Use the same amount of lean ground turkey and follow the recipe as written.
Can I make this casserole without cottage cheese?
Yes, but you’ll lose some protein and creaminess. You can replace it with more Greek yogurt, though the finished flavor will be tangier.
Will I taste the cottage cheese?
Not much. It is blended completely smooth with Greek yogurt, then mixed with strongly flavored taco ingredients.
Can I use flour tortillas?
Yes. Cut them into bite-sized pieces just like the corn tortillas. Expect a softer texture.
Can I make it spicier?
Yes. Use hot salsa or add jalapeños, cayenne, or crushed red pepper to the seasoned beef.
How do I keep Taco Casserole from getting watery?
Drain the beans and corn well, use thick salsa, and let the water added to the taco meat reduce before assembling the casserole.
How do I know when it is finished baking?
The casserole should be hot through the center, and the cheese should be completely melted with a few lightly browned areas.
