This Mexican-style penne bake combines savory ground beef, tangy salsa, and melted cheese for a filling meal. It is an efficient one-pan dinner that satisfies the whole family with minimal cleanup.

List of ingredients
- 1 pound ground beef – lean is preferred for less grease.
- 1 ounce (1 packet) taco seasoning – provides the primary flavor profile.
- 15 ounces (1 jar) chunky salsa – adds moisture and texture.
- 1 red bell pepper, chopped – adds color and sweetness.
- 1 teaspoon garlic powder – enhances the savory depth.
- 1 teaspoon onion powder – complements the garlic for a base flavor.
- 1 teaspoon dried oregano – provides an earthy, aromatic note.
- 12 ounces penne pasta (or your favorite pasta), cooked according to package directions for al dente – maintains structure during baking.
- 2 cups shredded Mexican blend or Monterey Jack cheese (divided) – used for the filling and the topping.
- 1/2 cup sour cream – creates a creamy bind for the pasta.
step-by-step instructions
- Brown the Beef: In a skillet, cook the ground beef until cooked through. Drain the excess fat to prevent a greasy casserole.
- Simmer the Sauce: Add the taco seasoning, salsa, chopped red bell pepper, garlic powder, onion powder, and dried oregano to the skillet. Bring the mixture to a boil and then immediately turn the heat off.
- Prepare the Pasta Mix: In a separate bowl, mix together the cooked pasta, 1 cup of the shredded cheese, and the sour cream until well coated.
- Layer the Casserole: Pour half of the creamy pasta mixture into a casserole dish. Top this layer with half of the meat mixture. Repeat the layers once more.
- Add the Topping: Sprinkle the remaining shredded cheese evenly over the top of the final meat layer.
- Bake: Place the dish in a preheated 350-degree F oven and bake for about 30 minutes.
- Garnish: Remove from the oven and garnish with fresh chopped cilantro before serving.
Pro Cooking Tips for Best Results
Maintain Al Dente Pasta Texture
It is critical to undercook the penne slightly before adding it to the dish. Since the pasta continues to cook in the oven with the sauce, starting with al dente noodles prevents them from becoming mushy.
Thoroughly Drain Ground Beef
Excess fat from the beef can separate and pool at the bottom of the casserole. Use a colander or a spoon to remove as much grease as possible after browning to ensure a clean flavor.
Preheat the Oven Fully
Ensure the oven reaches 350 degrees F before sliding the dish inside. This ensures the cheese melts and browns evenly and the center heats through in the allotted 30 minutes.
Even Layering Technique
Use a spatula to press the pasta and meat layers down gently. This removes air pockets and ensures that every serving has a balanced ratio of beef and noodles.
Ingredient Substitutions
Alternative Lean Proteins
If you prefer a lighter meat, substitute the ground beef with ground turkey or ground chicken. These options work well with the taco seasoning and salsa, though you may need less fat drainage.
Different Pasta Shapes
While penne is standard, rotini, fusilli, or bowtie pasta are excellent alternatives. These shapes have more ridges and spirals, which help the sauce and cheese cling to the pasta more effectively.
Cheese Variety Options
If Monterey Jack or a Mexican blend is unavailable, sharp cheddar or mozzarella can be used. Pepper Jack is a great choice if you want to add an extra kick of spice to the topping.
Sour Cream Replacements
Plain Greek yogurt is a suitable substitute for sour cream. It provides a similar tang and creamy consistency while adding a bit more protein to the dish.
Custom Flavor Variations
Adding Hearty Legumes
Stir in a can of drained black beans or pinto beans to the beef mixture. This adds more fiber and protein, making the meal even more filling and adding a traditional Mexican texture.
Incorporating Sweet Corn
Add half a cup of frozen or canned corn to the meat and salsa mixture. The sweetness of the corn balances the acidity of the salsa and the spice of the taco seasoning.
Increasing the Heat Level
For those who enjoy spicier food, add diced jalapeños or a pinch of cayenne pepper to the beef. You can also choose a “hot” variety of chunky salsa to elevate the heat.
Adding Extra Fresh Vegetables
Diced zucchini or corn can be sautéed with the bell pepper for added nutrition. Ensure the vegetables are chopped small so they integrate well with the penne pasta.
Serving and Pairing Ideas
Fresh Side Salads
Pair this rich casserole with a crisp garden salad or a Mexican slaw. A dressing with lime juice and cilantro helps cut through the richness of the cheese and sour cream.
Traditional Bread Pairings
Serve the dish with warm corn tortillas or a side of honey-glazed cornbread. The sweetness of cornbread complements the savory, spiced notes of the beef mixture.
Creamy Topping Additions
Offer a side of guacamole or sliced fresh avocados to add a cool, creamy element. A dollop of extra sour cream or a drizzle of ranch dressing also works well.
Bright Acidic Garnishes
Fresh lime wedges are an excellent addition to the plate. Squeezing fresh lime juice over the baked pasta right before eating brightens the overall flavor profile.
Storage and Preservation
Refrigeration Guidelines
Store leftover casserole in an airtight container in the refrigerator. It will stay fresh and safe to eat for up to 3 to 4 days.
Freezing for Later
This dish can be frozen by placing it in a freezer-safe container or wrapping individual portions in foil. It is best consumed within 3 months for optimal quality.
Preventing Dryness During Storage
When storing in the fridge, ensure the container is completely sealed. If the pasta seems to have absorbed too much sauce, add a teaspoon of water before reheating.
Reheating Instructions
Microwave Method
Place a portion in a microwave-safe dish and cover it with a damp paper towel. Heat on medium power in 1-minute intervals, stirring occasionally, until heated through.
Oven Reheating
Transfer leftovers to an oven-safe dish and cover with aluminum foil to retain moisture. Heat at 325 degrees F for 15-20 minutes or until the center is bubbling.
Stovetop Option
For smaller portions, you can reheat the casserole in a skillet over medium-low heat. Add a splash of beef broth or water to loosen the sauce as it warms.
Make-Ahead Advice
Pre-Assembling the Dish
You can assemble the entire casserole a day in advance and keep it refrigerated. When ready to bake, let it sit at room temperature for 20 minutes before putting it in the oven.
Component Preparation
Cook the beef mixture and the pasta on separate days to save time. Store them in separate containers and combine them just before the layering process.
Timing the Bake
If you are serving guests, you can do all the prep work in the morning. Simply slide the pre-assembled dish into the oven 45 minutes before dinner time.
Troubleshooting Common Issues
Fixing a Watery Casserole
If the dish appears too watery, it may be due to salsa with too much liquid. Next time, simmer the beef and salsa mixture for a few extra minutes to reduce the liquid before layering.
Preventing Overcooked Pasta
If your pasta often comes out too soft, reduce the boiling time by 2 minutes. The pasta should have a firm bite before it goes into the oven to withstand the baking process.
Stopping Cheese from Burning
If the cheese on top browns too quickly before the center is hot, cover the dish loosely with foil. This protects the topping while allowing the internal heat to rise.
Addressing Bland Flavor
If the dish tastes under-seasoned, add a pinch of salt or an extra sprinkle of taco seasoning to the beef. Ensure the salsa used has a bold flavor profile.
Frequently Asked Questions
Can I use different types of cheese?
Yes, any melting cheese works well. Cheddar, Monterey Jack, and Pepper Jack are the best choices for this specific flavor profile.
Is it possible to make this without sour cream?
You can use plain Greek yogurt or a mixture of cream cheese and a splash of milk. The purpose is to create a creamy bind for the pasta.
What is the best way to prevent the pasta from sticking?
Toss the cooked pasta with a small amount of olive oil or the sour cream mixture immediately after draining. This prevents the noodles from clumping together.
Can I add vegetables to the beef mixture?
Yes, diced onions, carrots, or spinach can be added. Just ensure they are cooked through with the beef before adding the salsa.
How do I know when the casserole is fully cooked?
The casserole is done when the cheese is melted and bubbling and the internal temperature reaches 165 degrees F.
Can I use a different oven temperature?
350 degrees F is ideal for melting cheese without burning it. If you use a higher temperature, you must reduce the baking time and monitor the top closely.
