How to make these Mexican Stuffed Shells Step by Step

Get the oven going and prepare a baking dish : Heat the oven to 350°F and spray a 2-quart casserole dish with cooking spray.

Cook the pasta : Cook 12 pasta shells al denté, drain, and rinse with cool water. Lay them open-side down, on a paper towel, to drain while you prepare the other ingredients .

Cook the onion and jalapeño: Heat a large skillet over medium heat. Add 1 tbsp of oil, 1 onion, and 1 jalapeño. Cook, stirring occasionally, until translucent and the onion becomes fragrant. This usually takes me about 4-5 minutes. Transfer the cooked vegetables to a paper towel to soak up any moisture.

Cook the beef : Add 1 lb. of ground beef to the skillet and cook, breaking the beef up with a spoon until it’s lightly browned. Drain any excess fat, leaving a small amount in the pan.

Add the seasonings : Stir in 2 tsp taco seasoning, 4 oz. cream cheese, 1 tsp salt, ½ tsp black pepper, 1 tbsp cilantro, ¼ cup taco sauce, and ½ cup shredded cheese into the beef mixture.

Cook: Cook for 2-3 minutes, over medium-low heat, until the mixture is hot and the cheese has melted. Remove from heat.

Coat the pan : Pour ¼ cup taco sauce into the prepared casserole dish and spoon it around so it covers the whole bottom of the pan.

Fill the shells: Fill each pasta shell with 2 tbsp of beef/cheese mixture and then place the shells, open side up, into the prepared dish, on top of the taco sauce. Pour the remaining taco sauce around and in between the shells.

Bake: Cover and bake 20 minutes.

Sprinkle with cheese and chips : Remove the dish from the oven, uncover, and sprinkle with 1 cup of crushed corn chips. Sprinkle the remaining cheese on top and bake about 10-15 minutes or until the cheese melts.

How to Store

These Mexican stuffed shells can be assembled up to 8 hours before you plan to bake them. Cover the pan and store it in the refrigerator until you’re ready. Increase the bake time accordingly.

These shells are a great freezer meal. I like to make a double batch and freeze one of the pans. If you freeze a pan of shells, make sure to cover it tightly with foil. If you use an aluminum pan, you can bake directly from frozen; if you use a glass pan, let the shells defrost in the fridge overnight.

When you are ready to eat, bake the shells directly from the freezer at 350°F for about 45 minutes with the foil, then remove it, and bake for an additional 15 minutes or until the shells are hot throughout.

Leftover shells will keep tightly covered or in an airtight container in the fridge for 3-4 days. Reheat in the microwave or in the oven. If you find they’ve dried out a bit, drizzle more taco sauce over them.

Freeze leftovers for up to 3 months.

Serving Suggestions

These taco stuffed shells taste so good with traditional taco toppings, so I like to top them with more taco sauce , creamy guacamole , and a few dollops of pico de gallo .

This Essential Grocery List is an absolute life saver for my family on the busy weeks. When I started this journey to learn how to cook, I quickly realized that the first step in cooking is having staple ingredients on hand. I want to avoid having to run out to the grocery store every single time I prepare a new recipe. Having a well-stocked pantry has made my life in the kitchen so much simpler, because when it’s time to cook, I have what I need.

Essential Grocery List

It’s so helpful to have a basic grocery list to help me remember which foods to buy at the store. This food shopping list is my go-to!

It’s better to stock up on things like grains, seasonings and spices, baking essentials, oils, condiments, canned and frozen foods, etc. so I can just grab them when I need them. These things have a long shelf life , so I keep them in my kitchen for convenience.

However, I do have to go to the supermarket sometimes, and there’s a way to make that trip easy and hassle-free: I keep a grocery list! If I go in blindly, I’ll leave with things I don’t need, and nothing that actually helps me prepare a good meal.

In the list below, I’ve compiled everything I always have on my stock-up grocery list.

I’ve got you covered! I created an easy grocery list filled with all of the essentials. Plus there’s a free printable version that you can take with you to the grocery store. It has everything you need to stock your pantry, your freezer, and your refrigerator.

What to Buy at the Grocery Store
