Make-Ahead Lasagna for a Group (with Strawberry Rhubarb Crisp)
Our group didn’t arrive until the afternoon today, so we only prepared one dinner service. That extra time was a welcome opportunity to do a bit of prep for tomorrow and to freeze a couple of pans to use later. I tested a new lasagna recipe that turned out very well; I doubled the batch, baking two pans today and sliding two pans into the freezer for another group later on.
This version is straightforward, scales well for larger crowds, and freezes nicely. Below are the ingredients and step-by-step layering instructions I used for two medium deep hotel pans. I recommend tasting and adjusting seasonings as you go—small tweaks make a big difference when you’re cooking in bulk.
For 2 medium deep hotel pans, use:
- 10 pounds ground beef
- 6 large onions, diced
- 1 bunch celery, diced
- 3 tablespoons minced garlic
- 3 tablespoons oregano
- 3 tablespoons Italian seasoning
- 2 large cans diced tomatoes
- 2 small cans tomato paste
- 2 cups ketchup (optional, I used this for a touch of sweetness and body)
- Salt and pepper to taste
Begin by browning the ground beef along with the diced onions, celery, and minced garlic until the meat is cooked through and the vegetables are softened. Add the diced tomatoes, tomato paste, oregano, Italian seasoning, and a couple of large pinches of salt and pepper. Simmer the sauce for about 30–45 minutes to let the flavors meld. Since I was making a double batch, I simmered each portion in its own pot so nothing boiled over and seasoning adjustments could be made independently. If desired, stir in the ketchup toward the end of simmering to round out the acidity and add a subtle sweetness.
The cheese filling I used for this quantity was hearty and binding, perfect for hotel pans:
- 4 containers cottage cheese (750 ml each)
- 10 eggs, beaten
- 3 cups grated Parmesan cheese
To assemble the lasagna, layer in the following order so each pan gets even distribution of sauce, noodles, and cheese. I used oven-ready lasagna noodles for convenience, which makes assembly quicker when you’re feeding a crowd.
- Begin with a thin layer of sauce across the bottom of the pan.
- Add a layer of oven-ready lasagna noodles.
- Spoon on a generous layer of sauce.
- Add another layer of oven-ready noodles.
- Cover with more sauce.
- Spread the cottage cheese mixture (cottage cheese + beaten eggs + Parmesan) evenly.
- Add a final layer of noodles.
- Top with remaining sauce.
- Finish with a layer of shredded mozzarella cheese for a gooey, browned topping.
Cover each pan with foil and bake for approximately one hour, keeping an eye on centers to ensure they heat through. If you’re freezing pans for later use, assemble them fully, wrap tightly with foil and plastic wrap, and label them with the date and contents. When reheating from frozen, allow adequate time for the center to come up to temperature—thawing in the refrigerator overnight before baking will reduce reheating time.
For this meal we served the lasagna with a classic Caesar salad, garlic toast, and strawberry rhubarb crisp for dessert. I used the same crisp method I usually make (I prepared four pans of crisp for the group), and it was a favorite—sweet, tart, and an easy make-ahead option that pairs nicely with a hearty main course.
The proportions in this lasagna were almost perfect for our crowd—enough to feed everyone comfortably with a little saved for later. The kids especially loved it, which is always the best compliment. Whether you’re cooking for volunteers, a retreat, or a busy household, this recipe scales well and takes advantage of the convenience of oven-ready noodles and make-ahead freezing. Small planning steps—like simmering sauce in separate pots when doubling a recipe and labeling frozen pans—make serving large groups much more manageable and stress-free.
