The Recipe How-To

Preparing the Cast Iron Sausage Lasagna

I recommend using a 12-inch cast iron skillet for this recipe but if you don’t have one, any oven-safe skillet or baking dish will work.

Step 1: Cook the Sausage and Onion

Heat 2 tablespoons of olive oil over medium-high heat in the cast iron skillet. Add 1 chopped onion and cook until softened for about 5 minutes. Next, add the sausage and hot red pepper flakes to the skillet. Use a wooden spoon to break up the sausage and cook until browned for about 10 minutes.

Step 2: Add Tomatoes and Spices

Add 2 minced garlic cloves to the skillet and cook for another minute. Pour in three 14-ounce cans of whole canned tomatoes with their juices into skillet. Crush tomatoes with your hands as you add them to the skillet. Stir in 1 tablespoon of fresh thyme leaves, 2 teaspoons of dried thyme leaves, salt and black pepper to taste.

Step3: Make Ricotta Cheese Mixture

In a separate medium mixing bowl, add one cup of whole milk ricotta cheese along with some chopped fresh basil leaves, salt and black pepper to taste. Mix well.

Step4: Layer Lasagna Noodles and Cheese Mixture

Preheat oven at 375°F or 190°C.
Place lasagna noodles on top of tomato-sausage mixture in an even layer that covers much of the sauce.
Using a spoon or spatula, spread the ricotta cheese mixture all over noodles evenly.

Step5: Add Cheese Toppings

Place slices of mozzarella cheese on top of ricotta mixture all over it ensuring every inch or two is covered in cheese. Sprinkle Parmesan cheese over mozzarella slices.

Step6: Bake it!

Repeat layers with remaining sauce and noodles until ingredients are gone.
Finally, bake in pre-heated oven at 375°F or 190°C for around half an hour until it’s bubbly hot and browned on top of cheese toppings & crispy around noodle edges.

You can consider making this warm and hearty dish any night of the week! Enjoy!

Substitutions and Variations

Lasagna is a versatile dish that can be customized to fit your preferences. Here are some substitution and variation ideas to add variety to this classic recipe.

– Vegetarian lasagna: For a vegetarian version of this recipe, omit the sausage and replace it with kale or another hearty green. You can also add sliced mushrooms for more texture and depth of flavor.

– Cheese lasagna: If you’re not a fan of meat, leave out the sausage altogether and make a three-cheese lasagna instead. Increase the amount of ricotta cheese, parmesan cheese, and mozzarella cheese to compensate for the loss of protein.

– Spicy sausage: If you like your lasagna with a bit of heat, use spicy Italian sausage instead of mild. Add red pepper flakes or cayenne pepper for an extra kick.

– Detroit-style pizza: Mix things up by layering the sausage on top of the noodles, rather than mixing it into the tomato sauce. This creates a “pizza” feel to your dish.

– Sausage and mushroom: Elevate your lasagna by adding sliced mushrooms to the tomato sauce before simmering it with the sausage. The earthy and meaty flavors will complement each other nicely.

No matter which substitution or variation you choose, remember that this recipe is all about making it your own. Experiment with different ingredients and techniques until you land on something you love.

Now that your cast iron sausage lasagna is ready, it’s time to decide how to serve and what to pair it with. Firstly, I would recommend letting it sit for a few minutes after taking it out of the oven, to allow the lasagna to set and make for easier cutting.

For a classic Italian experience, you can serve it with some garlic bread or focaccia on the side. Alternatively, a nice green salad with fresh produce like tomatoes, lettuce and arugula will make for a refreshing counterpart to the rich flavors of the lasagna.

You could also try pairing your sausage lasagna with a bold red wine like Zinfandel, Sangiovese or Barbera. The tannins in these wines complement the spices in the sausage while also standing up against the heavy cheese in the dish.

As for presentation, you can serve the cast iron skillet right at the table, letting guests scoop out their own portions. Or if you prefer more formal plating, you can transfer portions onto individual plates and garnish with fresh basil leaves and grated Parmesan cheese.

No matter how you choose to enjoy it, this cast iron sausage lasagna from America’s Test Kitchen recipe is sure to impress everyone at your dinner table.

Make-Ahead, Storing and Reheating

As with most lasagna recipes, this Cast Iron Sausage Lasagna is a great candidate for making ahead of time. In fact, I recommend preparing it a day in advance to allow the flavors to meld together and the lasagna to set up properly. To make this dish ahead of time, simply prepare everything as directed and cover tightly with foil or plastic wrap. Then, refrigerate until you’re ready to bake.

When it comes to storing leftovers, make sure you remove any remaining portions from the cast iron skillet and transfer them to an airtight container. You can store leftovers in the refrigerator for up to 4 days or freeze them for up to 3 months. When reheating, I recommend using the oven instead of the microwave as it will help ensure that the lasagna heats evenly and the cheese stays nice and gooey.

To reheat leftover lasagna in the oven, preheat your oven to 350°F. Then, wrap your leftover lasagna in aluminum foil and place it on a baking sheet. Bake for about 25-30 minutes or until heated all the way through. If you’re reheating frozen leftovers, adjust your baking time accordingly and expect it to take at least an hour.

It’s worth noting that this lasagna recipe is quite versatile and you could easily swap out the sausage for other proteins such as ground beef or even kale for a vegetarian twist on classic lasagna. The possibilities are endless!

Tips for Perfect Results

Cooking a sausage lasagna in a cast iron skillet requires some tips to achieve the perfect outcome. Here are some helpful tricks to keep in mind before starting to cook.

Firstly, it is best to use hot Italian sausage in the recipe for added flavor. Its spiciness will complement the other ingredients’ taste and enhance the overall flavor of the dish. However, if you prefer a milder taste, you can always substitute it with ground beef or mild Italian sausage.

Another thing to note is that it’s best to cook the sausage in a large cast-iron skillet over medium-high heat. This will allow the meat to brown evenly and give it a nice texture without getting burnt. Using a smaller skillet will cause the sausage to cook unevenly and become mushy.

In addition, be sure not to overcrowd the skillet with too many ingredients as this can affect the overall texture and flavor of the lasagna. Instead, layer them carefully while keeping everything in moderation.

Furthermore, to add a depth of flavor, incorporate some fresh herbs such as thyme or basil into the tomato sauce. Using dried herbs is also acceptable if fresh ones are unavailable.

When assembling the lasagna, remember to spread each layer of cheese and sauce out evenly across the noodles before adding another layer. This ensures that every bite has an equal amount of flavorful cheese and rich tomato sauce.

Lastly, after baking your lasagna in the cast-iron skillet, let it rest for at least 10 minutes before serving. This allows all of the flavors to combine and settle into each bite.

By following these tips and tricks, you’re guaranteed perfect results for your cast iron sausage lasagna every time.

How to cook sausage in cast iron skillet in oven?

Here’s a nifty trick for cooking sausages done in a jiffy. Pop your sausages into a cast-iron skillet at room temperature, then place it inside the cold oven.
