Ingredients
- 1 lb. ground beef
- 1 onion, diced
- 3 cloves garlic, minced
- 10 oz bag fresh spinach
- 1 cup water
- 2 lbs. ricotta cheese
- 1 cup Italian blend cheese, shredded
- 12 oz jumbo pasta shells, cooked according to package directions
- 56 oz pasta sauce (2 standard jars)
Instructions
- Brown the ground beef with the diced onion and minced garlic in a large skillet over medium-high heat. Cook until the beef is no longer pink and the onion is translucent. Drain any excess fat.
- While the beef is browning, cook the fresh spinach. Place the spinach in a pot with 1 cup of water. Cook over medium heat until the spinach is soft and completely wilted, which usually takes about 3-4 minutes. Once cooked, drain the spinach thoroughly and squeeze out as much excess water as possible. This step is crucial to prevent a watery filling. Chop the drained spinach.
- In a large mixing bowl, combine the browned ground beef mixture, chopped spinach, ricotta cheese, and shredded Italian blend cheese. Mix well until all ingredients are evenly incorporated. This is your delicious filling!
- Prepare your baking pans. Spread approximately half of one jar of pasta sauce on the bottom of a 9×13 inch baking pan. This will prevent the shells from sticking and add moisture.
- Carefully fill each cooked jumbo pasta shell with the beef and spinach mixture. Arrange half of the stuffed shells in the prepared 9×13 inch baking dish. Cover these shells with the remaining pasta sauce from the first open jar.
- Cover the baking pan tightly with aluminum foil. Bake in a preheated oven at 350°F (175°C) for 45 minutes, or until bubbly and heated through. Let it rest for a few minutes before serving.
- For the second batch, place the other half of the stuffed shells on a flat, parchment-lined baking sheet and freeze them until solid. Once frozen, transfer the individual shells to a freezer-safe container or a large freezer bag. Label the container with “Stuffed Shells: Thaw, place in pan and cover with foil, and bake at 350°F for 45 minutes.” Return to the freezer. Save the unopened second jar of pasta sauce in your pantry to use when you bake the frozen shells.

Key Ingredients and Smart Tips
Every great recipe starts with quality ingredients. For our Spinach and Ground Beef Stuffed Shells, each component plays a vital role in building the overall flavor and texture:
- Ground Beef: Choose a lean-to-medium ground beef (85-90% lean) for good flavor without excessive grease. The beef provides a robust, savory base for the filling. For a lighter option, you can substitute with ground turkey or a mix of beef and Italian sausage for added spice.
- Onion and Garlic: These aromatic vegetables are essential for building a deep, savory flavor profile. Dicing the onion finely ensures it blends seamlessly into the filling, while minced garlic provides that classic Italian aroma. Don’t skimp on the garlic!
- Fresh Spinach: While frozen spinach can work in a pinch, fresh spinach offers a brighter flavor and better texture once cooked down. The key is to thoroughly drain and squeeze out all excess water after wilting. This prevents the filling from becoming watery and ensures a firm, creamy consistency. A simple way to do this is by placing the cooled spinach in a clean kitchen towel and twisting to wring out the liquid.
- Ricotta Cheese: This is the heart of the creamy filling. Full-fat ricotta provides the richest flavor and best texture, but part-skim can be used if you prefer a lighter dish. Ensure your ricotta is fresh for optimal taste.
- Italian Blend Cheese: A good shredded Italian blend cheese (often a mix of mozzarella, provolone, parmesan, and romano) adds another layer of cheesy goodness and helps bind the filling. You can also use just mozzarella or a combination of mozzarella and grated Parmesan for a different cheesy dynamic.
- Jumbo Pasta Shells (Conchiglie): These large shells are perfect for stuffing as they hold a generous amount of filling. Cook them al dente, according to package directions, but be careful not to overcook them, as they need to hold their shape during stuffing and baking. Rinse them with cold water after cooking to prevent sticking and stop the cooking process.
- Pasta Sauce: A good quality jarred pasta sauce is a fantastic time-saver. Choose your favorite marinara, arrabbiata, or a classic tomato and basil sauce. If you have a homemade sauce recipe, feel free to use that for an extra touch of personalization.
Detailed Preparation and Cooking Tips
Creating these stuffed shells is straightforward, but a few tips can make the process even smoother:
- Browning the Beef and Aromatics: Start with a hot skillet. Browning the ground beef, onion, and garlic thoroughly develops deep flavors. Make sure to break up the beef into small crumbles. After browning, drain any accumulated fat. This step is crucial for preventing a greasy final dish and ensures the filling has the right texture.
- Wilting and Draining Spinach: Don’t skip the step of squeezing excess water from the spinach. As mentioned, waterlogged spinach will lead to a soggy filling. After wilting and cooling slightly, gather the spinach in your hands or a cheesecloth and squeeze firmly until no more liquid comes out. The dryer the spinach, the better the filling’s texture will be.
- Mixing the Filling: Use a large bowl to give yourself plenty of space to mix the beef, spinach, and cheeses. A rubber spatula or your hands work best for ensuring everything is thoroughly combined. Taste a small bit of the mixture (if safe to do so, or adjust seasoning based on experience) and add salt, pepper, or other Italian herbs like oregano or basil if desired.
- Stuffing the Shells: This is the most hands-on part. You can use a small spoon to fill each shell, or for quicker stuffing, use your hands. Don’t overfill the shells; a level tablespoon or two per shell is usually sufficient. Arrange them snugly in the baking dish, but not so tight that the sauce can’t circulate.
- Sauce Application: A thin layer of sauce on the bottom of the pan prevents sticking and adds moisture from the start. Covering the shells with sauce during baking keeps them moist and ensures they cook evenly.
- Baking Covered: Baking covered with foil helps the shells steam and ensures the filling heats through without the top becoming dry or burnt. You can remove the foil for the last 5-10 minutes if you like a slightly browned, bubbly cheese topping.
Mastering the Make-Ahead and Freezing Process
The beauty of this recipe lies in its freezer-friendliness. Here’s a more comprehensive guide to making and freezing these delicious stuffed shells:
Preparing for Freezing:
Once you’ve stuffed the shells, you have a choice: assemble one pan for immediate baking and freeze the individual shells for the other batch. This method of freezing shells individually prevents them from sticking together and makes it easier to portion them later.
- Flash Freeze: Place the unstuffed, filled shells in a single layer on a parchment-lined baking sheet. Ensure they are not touching. Place the baking sheet in the freezer for 1-2 hours, or until the shells are firm and frozen solid. This “flash freezing” step is crucial.
- Transfer to Storage: Once flash-frozen, transfer the solid shells to heavy-duty freezer bags or airtight freezer-safe containers. Remove as much air as possible from bags to prevent freezer burn.
- Label Clearly: Label the bags/containers with the date and cooking instructions: “Stuffed Shells (Date): Thaw, place in a 9×13 pan, cover with 28 oz pasta sauce and foil, bake at 350°F for 45-60 minutes, or until heated through.” Don’t forget to note that an extra jar of sauce is needed.
Storage Duration:
Properly stored, frozen stuffed shells will maintain their quality for up to 3 months in the freezer.
Cooking from Frozen:
For best results, it’s recommended to thaw the frozen shells in the refrigerator overnight before baking. However, you can bake them from frozen, although it will require a longer cooking time. If baking from frozen, place the shells in a baking dish, cover with sauce and foil, and bake at 350°F (175°C) for approximately 60-75 minutes, or until thoroughly heated and bubbly. Ensure the internal temperature reaches 165°F (74°C).
Exciting Variations and Substitutions
This recipe is incredibly versatile, allowing for many delicious variations to suit different tastes and dietary needs:
- Meat Alternatives: Instead of ground beef, try ground Italian sausage (sweet or spicy), ground turkey, or even a mix of ground beef and sausage. For a vegetarian option, substitute the meat with sautéed mushrooms, cooked lentils, or plant-based ground “meat.”
- Cheese Swaps: Experiment with different cheeses! Add some grated Parmesan cheese to the filling for a saltier, sharper flavor, or replace the Italian blend with fresh mozzarella for extra gooeyness. A dollop of cream cheese in the filling can also add a delightful tang and creaminess.
- Vegetable Boost: Enhance the nutritional content and flavor by adding more vegetables. Sautéed bell peppers, zucchini, or finely diced carrots can be cooked with the onion and garlic. You could also stir in some chopped sun-dried tomatoes or a handful of fresh basil into the filling.
- Sauce Personalization: While jarred sauce is convenient, feel free to use your favorite homemade marinara. For a richer flavor, consider a creamy tomato sauce or a rosé sauce. A splash of red wine or a pinch of red pepper flakes can also elevate the store-bought sauce.
- Gluten-Free Option: Many brands now offer gluten-free jumbo pasta shells. Just be sure to cook them carefully as gluten-free pasta can sometimes be more delicate.
Perfect Pairings and Serving Suggestions
These hearty stuffed shells are a complete meal on their own, but they pair wonderfully with a few simple sides to create a well-rounded Italian feast:
- Fresh Green Salad: A crisp green salad with a light vinaigrette provides a refreshing contrast to the rich pasta.
- Garlic Bread or Crusty Bread: Perfect for soaking up every last bit of that delicious pasta sauce.
- Steamed Vegetables: A side of steamed broccoli, green beans, or asparagus adds color and nutrients.
- Red Wine: A medium-bodied red wine, such as Chianti or Merlot, complements the flavors of the dish beautifully.
Frequently Asked Questions (FAQs)
- Can I use frozen spinach instead of fresh?
- Yes, you can! If using frozen spinach, make sure to thaw it completely and squeeze out all the excess water thoroughly. This is even more crucial with frozen spinach as it tends to hold more water than fresh.
- How many shells does this recipe make?
- A 12 oz box of jumbo pasta shells typically contains about 40-50 shells. This recipe is designed to fill a quantity that will yield two 9×13 inch pans, which usually means using most of a standard box of shells.
- Can I prepare the filling ahead of time?
- Absolutely! You can mix the ground beef and spinach filling up to 24 hours in advance and store it in an airtight container in the refrigerator. Stuff the shells just before baking or freezing.
- What if I don’t have Italian blend cheese?
- You can use a combination of shredded mozzarella and grated Parmesan cheese. About 3/4 cup mozzarella and 1/4 cup Parmesan would be a good substitute for the Italian blend.
- How do I know the shells are fully cooked when baking from frozen?
- The internal temperature of the filling should reach 165°F (74°C). You can check this with a meat thermometer. The sauce should be bubbly, and the cheese melted and lightly golden on top.
