I fall for this casserole every time because it reads like two favorites in one: hearty beef taco filling and the comfort of a cheese-and-tortilla bake. It’s built in layers, feeds a crowd, and hits that thin line between casual and celebratory. The topping of avocado, tomato, and broken tortilla chips gives it a fresh crunch that keeps the dish lively rather than heavy.

There’s no fuss here—just honest components stacked and baked until bubbly. You can have this on the table on a weeknight with minimal planning, or pull it out for Sunday supper when you want something convivial and forgiving. I’ll walk you through the exact steps and then give practical swaps, storage tips, and troubleshooting so you get consistent results every time.

Ingredients at a Glance

1 1/2 pounds organic ground beef — the base protein; browns up with a nice flavor and holds the layers together.
1 teaspoon seasoned salt — adds savory depth; taste and adjust if your taco seasoning is salty.
1 package taco seasoning — quick flavor shortcut that gives the filling its Tex-Mex profile.
1 can (14.5 oz) petite diced tomatoes, undrained — provides moisture and a bit of tomato texture in the sauce.
1 can (15 oz) tomato sauce — smooths and stretches the tomato base so the casserole isn’t too chunky.
1 can (4 oz) chopped green chilies — brings mild heat and a subtle smokiness.
2 cups (16 oz) 4% cottage cheese — combines with eggs to make a creamy, slightly tangy layer that stands in for ricotta.
2 eggs (lightly beaten) — bind the cottage cheese so the layer slices cleanly.
12 small corn tortillas (torn) — they act like lasagna noodles, absorbing sauce and providing structure; tearing helps them distribute evenly.
3 ½ – 4 cups shredded Cheddar & Monterey Jack Cheese — the melty, gooey glue that finishes each layer; split evenly between the two layers as directed.
Toppings — finishing mix for texture and freshness: broken tortilla chips, salsa, diced tomatoes, and chunked avocados.
2–3 cups tortilla chips (broken into med/large pieces) — add crunch on top right before serving so they don’t get soggy.
Salsa of your choice — a flavor amplifier; use chunky or smooth based on preference.
3 tomatoes (diced) — brightens the dish and adds acidity.
3 avocados cut into chunks — creamy counterpoint that cools the spice and adds richness.

Directions: Texas Style Lasagna

Preheat oven to 350°F (175°C). Grease an 11×7-inch baking dish.
In a large skillet over medium-high heat, brown 1 1/2 pounds organic ground beef until no pink remains. Drain excess fat.
Return the beef to the skillet. Add 1 teaspoon seasoned salt, 1 package taco seasoning, 1 can (14.5 oz) petite diced tomatoes (undrained), 1 can (15 oz) tomato sauce, and 1 can (4 oz) chopped green chilies. Reduce heat to medium-low and simmer uncovered, stirring occasionally, for 15–20 minutes.
While the meat simmers, lightly beat 2 eggs in a small bowl, then stir in 2 cups (16 oz) 4% cottage cheese until combined.
Tear the 12 small corn tortillas into pieces (they should be in torn pieces as listed).
Divide the meat sauce, torn tortillas, cottage cheese mixture, and shredded cheese into two equal portions. (The shredded Cheddar & Monterey Jack cheese total is 3½–4 cups; divide evenly between the two layers.)
Assemble in the greased 11×7 dish: spread half of the meat sauce in the bottom, scatter half of the torn tortillas over the sauce, spread half of the cottage cheese and egg mixture evenly, and top with half of the shredded cheese.
Repeat the layers: remaining meat sauce, remaining torn tortillas, remaining cottage cheese and egg mixture, and remaining shredded cheese.
Bake uncovered at 350°F for 30 minutes, or until the casserole is hot and bubbly and the cheese is melted.
Remove from the oven and let stand for 5 minutes.
Top with 2–3 cups tortilla chips (broken into medium/large pieces), 3 avocados cut into chunks, 3 tomatoes diced, and salsa of your choice.
Serve immediately.

Why It Works Every Time

This recipe relies on straightforward chemistry: protein and tomato form a saucy, meaty base; torn corn tortillas absorb that sauce and provide structure; a cottage cheese-and-egg layer gives creaminess without becoming runny; and the shredded cheeses melt and bind everything. Tearing the tortillas instead of layering whole pieces prevents dry pockets and ensures even sauce distribution. Simmering the meat mixture reduces excess liquid so the bake sets correctly during the oven time.

The final fresh toppings do two jobs. Avocado and tomato cut through the richness, while tortilla chips add a textural high note. That contrast—creamy, acidic, crunchy—is what keeps this casserole from feeling one-note and why leftovers reheat well.

Low-Carb/Keto Alternatives

Skip the tortilla chips and broken tortillas — layer thinly sliced zucchini or eggplant instead. They won’t precisely match the texture but will keep carbs low.
Replace cottage cheese — if you’re staying very low-carb, use a higher-fat cream cheese blend (spreadable) to maintain creaminess; expect a richer bite.
Watch the salsa — choose a low-sugar, fresh salsa or a pico de gallo to cut carbs from commercial jarred varieties.

What’s in the Gear List

11×7-inch baking dish — fits the recipe volume and bakes evenly.
Large skillet — for browning beef and simmering the sauce.
Mixing bowl — to combine eggs and cottage cheese.
Measuring cups and spoons — accurate seasoning helps balance the bake.
Spatula or wooden spoon — for stirring and spreading layers cleanly.

Frequent Missteps to Avoid

Skipping the simmer — if you don’t reduce the meat sauce, the bake can be watery and won’t set properly.
Using whole tortillas — whole or folded tortillas can create soggy layers and uneven texture; tearing them distributes the starch and prevents dense pockets.
Overbaking — bake just until bubbly and the cheese is melted. Overbaking dries out the edges and toughens the tortillas.
Adding toppings too early — add chips, avocado, and fresh tomato after baking. If baked with the casserole they lose crunch and the avocado browns.
Not draining excess fat — drain the browned beef to prevent a greasy final dish.

Season-by-Season Upgrades

Spring: Brighten the topping with fresh cilantro and a squeeze of lime. If you have early tomatoes, use those for a sweeter pop.

Summer: Take advantage of peak tomatoes and add a spoonful of homemade salsa fresca. Serve alongside a light corn salad or pickled jalapeños.

Fall: Fold in a cup of roasted poblano or corn to the meat sauce for additional depth. Serve with warm beans and cornbread for a heartier spread.

Winter: Top with pickled red onions and serve with a side of roasted winter squash to add seasonal richness that pairs with the Tex-Mex flavors.

Notes from the Test Kitchen

We tested this casserole with a few variations to find the most reliable method. Tearing the corn tortillas into pieces rather than using whole rounds is non-negotiable for even saucing and texture. We also found that cottage cheese at 4% strikes the best balance: it’s creamy and holds up in the bake without separating.

If you prefer a spicier profile, add a half to one teaspoon of chili powder during the simmer or a can of diced tomatoes with green chiles for extra heat. If you like it milder, omit the chopped green chilies or use mild salsa as a topping.

How to Store & Reheat

Cool the casserole to room temperature, then cover tightly and refrigerate for up to 3 days. To freeze, assemble and bake as directed, cool completely, then wrap tightly with foil and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Reheat portions in a 350°F oven covered with foil for 15–20 minutes from chilled, or until heated through. Microwaving works for single servings—cover loosely and heat in 45–60 second intervals, stirring or repositioning the portion between bursts to distribute heat evenly. Add fresh toppings after reheating; do not reheat with the chips or avocado on top.

Ask the Chef

Q: Can I use flour tortillas instead of corn? A: You can, but corn tortillas give the authentic texture and handle the sauce differently. Flour will be softer and may make the casserole a touch denser. If you use flour, lightly toast them first to reduce sogginess.

Q: Can I make this vegetarian? A: Replace the ground beef with a seasoned lentil or textured vegetable protein mixture and keep the same sauce proportions. Increase the simmer time slightly so the filling thickens.

Q: Why not use ricotta? A: Cottage cheese is used here for its tang and looser curd; it mixes easily with eggs and binds without separating. If you prefer ricotta, expect a slightly different texture but it will still work.

Save & Share

This is the kind of casserole worth bookmarking. It travels well to potlucks, keeps nicely for leftovers, and scales up if you double the recipe in a larger pan. If you make it, save the digital photo and tag it when you share—people always ask for the recipe after the first bite. And if you tweak it, note what you changed so the next bake is just as good.
