Ingredients & Quantities
This recipe makes a generous 9×13 inch casserole, perfect for feeding a large family or ensuring plenty of leftovers.
For the Casserole Base:
- 1 pound Medium Pasta Shells, Elbows, or Rotini
- 1 Tablespoon Olive Oil
- 1 pound Lean Ground Beef (90/10 ratio is ideal)
- 1 package (1 ounce) Taco Seasoning Mix
- 1/2 cup Water
- 1 cup Salsa (medium heat recommended)
- 1 cup Sour Cream (full-fat or reduced fat)
- 1/2 cup Milk (whole milk or 2%)
- 1/2 teaspoon Salt
- 1/4 teaspoon Black Pepper
For the Cheese & Toppings:
- 2 cups Shredded Cheddar Cheese (or Mexican blend), divided
- 1/2 cup Chopped Black Olives (optional)
- 1/2 cup Chopped Cilantro, for garnish
- 1 cup Crushed Tortilla Chips (for serving)

Step-by-Step Instructions
- Cook Pasta: Preheat oven to 375°F (190°C). Cook the 1 pound of pasta according to package directions until al dente (still slightly firm). Drain the pasta and set aside.
- Cook Meat: While the pasta cooks, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the 1 pound ground beef and cook, breaking it up, until browned. Drain any excess grease.
- Season Meat: Stir in the 1 package taco seasoning mix and 1/2 cup water. Bring to a simmer and cook for 5 minutes, until the sauce thickens slightly.
- Create Creamy Sauce: Remove the meat from the heat. Stir in the 1 cup salsa, 1 cup sour cream, 1/2 cup milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mix well until the sauce is uniform and creamy.
- Assemble Filling: Add the cooked, drained pasta and 1 cup of shredded cheddar cheese (save the rest for the topping) to the meat and sauce mixture. Stir until everything is evenly coated. Pro Tip: Add the optional 1/2 cup black olives now for extra flavor.
- Bake: Transfer the entire mixture to a lightly greased 9×13 inch baking dish. Sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the top.
- Cook: Bake for 25–30 minutes, or until the casserole is hot throughout and the cheese on top is melted, golden brown, and bubbly.
- Serve: Let the casserole rest for 5 minutes before serving. Garnish with fresh cilantro and crushed tortilla chips for a final crunch.
Storage & Freezing
- Fridge: Store cooled leftovers in an airtight container for up to 4 days. The pasta will absorb more liquid as it sits, making it even thicker.
- Reheating: Reheat individual portions in the microwave. Reheat the entire casserole (covered with foil) in the oven at 350°F until warm.
- Freezing (Unbaked): Assemble the casserole (do not add the top layer of cheese). Cover tightly with plastic wrap and foil and freeze for up to 3 months. Thaw overnight in the fridge and add the top layer of cheese right before baking.

Frequently Asked Questions
Can I make this vegetarian? Yes! Substitute the ground beef with 1 pound of plant-based ground meat substitute, or use 1 can each of rinsed and drained black beans and kidney beans for a hearty meatless base.
What kind of pasta should I use? Short, sturdy pasta shapes work best to hold the heavy sauce. Medium shells, elbow macaroni, rotini, or even penne are excellent choices.
How can I make the spice level hotter? Use a “hot” variety of salsa, add a diced jalapeño when sautéing the meat, or stir in a teaspoon of chili powder or cayenne pepper with the taco seasoning.
