Busy weeknights often leave little time for cooking from scratch. These casseroles are made to prepare in advance and store in the freezer without much fuss. You will find 11 practical recipes below that work well for batch cooking. Each one focuses on simple ingredients and straightforward steps to help with meal planning.
Helpful Tips Before You Start
These tips will help your casseroles stay fresh in the freezer and reheat without losing texture.
Cool Completely First
Let casseroles reach room temperature after baking. Then chill them in the fridge for an hour before freezing to cut down on ice crystals.
Use Proper Wrapping
Wrap pans tightly in plastic wrap followed by a layer of foil. This keeps air out and prevents freezer burn during longer storage.
Portion Before Freezing
Divide large casseroles into meal-sized sections. Smaller portions thaw faster and make weeknight dinners quicker to pull together.
Label with Dates
Write the recipe name, date, and reheating oven temperature on each container. Most of these casseroles keep well for up to three months.
Thaw in the Fridge
Move a frozen casserole to the refrigerator the night before you need it. This slow thaw helps the center heat evenly without drying the edges.
Beef Lasagna with Spinach and Ricotta
This lasagna makes an easy option for meal prep because you can assemble the whole dish and freeze it for busy nights ahead. The layers hold up well after reheating, giving you a complete dinner with protein, vegetables, and cheese in one pan.
It tastes hearty and comforting with a savory beef sauce, creamy ricotta pockets, and tender noodles. The spinach blends into the filling without changing the classic lasagna texture.
Serves 4 people.
Ingredients
- 9 lasagna noodles
- 1 pound ground beef
- 1 small onion, diced
- 3 cloves garlic, minced
- 24 ounces marinara sauce
- 10 ounces frozen spinach, thawed and squeezed dry
- 15 ounces ricotta cheese
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
Instructions
- Bring a large pot of salted water to a boil and cook the lasagna noodles until just al dente. Drain and set aside.
- In a large skillet over medium heat, cook the ground beef with the diced onion until the beef is browned. Add the minced garlic and cook for one more minute.
- Stir the marinara sauce, Italian seasoning, salt, and pepper into the beef mixture. Simmer for 5 minutes, then remove from heat.
- In a mixing bowl, combine the ricotta cheese, thawed spinach, and half of the Parmesan cheese.
- Spread a thin layer of beef sauce in the bottom of an 8×8 baking dish. Add a layer of noodles, then half the ricotta mixture, followed by a third of the mozzarella. Repeat the layers once more, ending with the remaining beef sauce and mozzarella on top. Sprinkle with the rest of the Parmesan.
- Cover the dish tightly with foil and freeze for up to two months, or bake at 375°F for 25 minutes until bubbly.
Extra Tips
Assemble the lasagna right up to the freezing step so the noodles do not absorb too much sauce. When you are ready to eat, thaw it overnight in the fridge before baking to keep the layers even. If you want a stronger spinach flavor, you can swap in fresh spinach that has been wilted and drained.Course: Main Course Cuisine: Italian Equipment: Large pot, Large skillet, Mixing bowl, 8×8 baking dish
