These taco stuffed shells have completely revolutionized my weeknight dinner game. I stumbled on this recipe a few years back when I was bored with regular tacos but had a craving for Mexican flavors. The combination of jumbo pasta shells with seasoned taco meat and melty cheese creates this perfect fusion dish that somehow satisfies both pasta and taco cravings simultaneously.

Last month, I made these for my neighbor who just had a baby. Her husband texted me the next day saying even their toddler, who normally refuses anything but chicken nuggets, ate three shells and asked for "taco boats" again. When you can please both sleep-deprived parents and a finicky 3-year-old, you know you've got a winner.

Key Ingredients

  • Jumbo pasta shells: Cook these just to al dente as they'll continue to absorb moisture in the oven. Overcooking leads to torn shells that won't hold your filling.
  • Ground beef: I use 85/15 lean-to-fat ratio for the best flavor without excessive grease. Ground turkey works beautifully too if you prefer.
  • Taco seasoning: Store-bought packets work perfectly, but I often make my own to control the salt and heat levels.
  • Two cheese blend: The combination of sharp cheddar and creamy Monterey Jack creates the perfect melt and flavor. Freshly grated melts so much better than pre-shredded.
  • Rotel tomatoes: These add amazing flavor and a touch of heat. The green chilies in them complement the taco flavors perfectly.
  • Fresh jalapeño: This adds a bright, fresh heat that balances the rich filling. Adjust according to your family's spice tolerance.

Shell-Stuffing Magic

Perfect pasta cooking
Cook those shells just until they're flexible but still firm. They should hold their shape when handling but be pliable enough to stuff. A minute under the package directions usually works perfectly.
Flavor-building strategy
Sautéing the onions with the beef (rather than adding them raw) develops a depth of flavor that makes all the difference. Let them get slightly golden for the best taste.
Cooling before cheese
That brief cooling period before adding the cheese to the filling prevents it from immediately melting, which would make the filling runny and difficult to stuff into the shells.
Stuffing technique
A small spoon works well for filling, but my secret weapon is a cookie scoop! It portions perfectly and keeps your hands clean during assembly.
Covering while baking
Baking covered for most of the time prevents the shells from drying out while ensuring everything heats through. That final uncovered bake lets the cheese get perfectly melty and bubbly.
Serve promptly
These are at their absolute best right from the oven when the cheese is gooey and the shells are perfectly tender but still hold their shape.

I perfected this recipe after noticing how my family seemed to get bored with our regular taco Tuesday routine. My first attempt used too much salsa and resulted in soggy shells. After adjusting the liquid ratios and adding that crucial covered baking step, I finally nailed the perfect balance of flavors and textures. My teenage son now requests these for his birthday dinner every year, which I consider the highest compliment a recipe can receive.

Serving Ideas

Serve these shells with a side of Mexican street corn or a simple green salad with lime vinaigrette. Set up a topping bar with sour cream, guacamole, extra salsa, and chopped cilantro so everyone can customize their shells. For a complete fiesta, add a side of black beans and Mexican rice.

Tasty Twists

Try using ground chicken or turkey seasoned with chipotle powder for a smoky variation. Add a layer of refried beans to the bottom of the baking dish before adding the shells for extra fiber and flavor. For a vegetarian version, substitute the beef with a mixture of black beans and corn.

Storage Smarts

These shells keep beautifully in the refrigerator for up to 3 days. The microwave works for quick reheating, but for best results, cover with foil and warm in a 300°F oven for about 20 minutes. You can also assemble the entire dish a day ahead, refrigerate, and add about 10 minutes to the covered baking time when you're ready to cook.

Ingredients

→ For the Shells

01 20-24 jumbo shell pasta
02 1 pound ground beef
03 1 medium onion, diced
04 3 tablespoons taco seasoning
05 3/4 cup water
06 1 cup salsa or salsa style tomatoes
07 1 cup shredded cheddar cheese
08 1 cup shredded Monterey Jack cheese
09 1 (10 ounce) can Rotel tomatoes, drained (or diced tomatoes)
10 1 jalapeño or serrano pepper, finely minced
11 Green onions, chopped (optional, for garnish)

Instructions

Step 01

Preheat oven to 350°F (175°C). Spray a 9x13 inch baking dish with nonstick cooking spray.

Step 02

Bring a large pot of water to boil. Cook the jumbo shells according to package directions until al dente. Drain well and set aside to cool slightly.

Step 03

While pasta cooks, brown the ground beef over medium-high heat in a large skillet. When it's about halfway browned, add the diced onion and continue cooking until the beef is fully browned and the onions are soft. If needed, drain excess grease.

Step 04

Add the taco seasoning and water to the ground beef mixture. Simmer for 10 minutes, allowing the flavors to combine and the liquid to reduce. Stir in the salsa and remove from heat. Let cool for a few minutes.

Step 05

Once slightly cooled, stir half of the cheddar cheese and half of the Monterey Jack cheese into the beef mixture.

Step 06

Spoon the seasoned ground beef mixture into the cooked pasta shells and arrange them in a single layer in the prepared baking dish.

Step 07

Top the filled shells with the remaining cheese, drained Rotel tomatoes, and minced jalapeño. Cover with foil and bake for 20 minutes. Then uncover and bake for an additional 5 minutes until cheese is bubbly and lightly browned.

Step 08

Sprinkle with additional minced jalapeño or green onions if desired. Serve promptly for best results.

Notes

  1. Wear gloves when mincing jalapeños or hot peppers, or at least wash hands thoroughly and avoid touching your face
  2. To reduce heat from peppers, remove the seeds and veins with a spoon
  3. Leftovers can be stored in an airtight container for up to 3 days
