Preparing lasagna for a large group can seem daunting, but with careful planning and scaled ingredients, you can serve a delicious, hearty dish to 100 guests. This recipe is designed to be straightforward, ensuring consistent results and maximum flavor in large batches, perfect for events, catering, or big family gatherings.
Ingredients
- Ground beef or Italian sausage – 10 pounds (4.5 kg)
- Onions, finely chopped – 4 large (about 2 pounds / 900 g)
- Garlic cloves, minced – 20 cloves
- Crushed tomatoes – 20 pounds (9 kg)
- Tomato paste – 4 cups (950 ml)
- Olive oil – 1 cup (240 ml)
- Fresh basil, chopped – 1 cup (about 30 grams)
- Fresh oregano, chopped – ½ cup (about 15 grams)
- Sugar – 4 tablespoons
- Salt and pepper – to taste
- Ricotta cheese – 10 pounds (4.5 kg)
- Shredded mozzarella cheese – 15 pounds (6.8 kg)
- Grated Parmesan cheese – 4 pounds (1.8 kg)
- Lasagna noodles – approximately 45-50 pounds (20-23 kg), depending on size and layering
Instructions
- Prepare the Meat Sauce: In large, heavy-bottomed pots or multiple stockpots, heat olive oil over medium-high heat. Add chopped onions and sauté until translucent, about 5 minutes. Add minced garlic and cook for another minute. Incorporate ground beef or sausage, breaking it apart with a spoon, and cook until browned and cooked through, about 10 minutes. Drain excess fat if necessary.
- Add Tomatoes and Seasonings: Stir in crushed tomatoes, tomato paste, chopped basil, oregano, sugar, salt, and pepper. Bring to a simmer, then reduce heat to low. Let the sauce simmer uncovered for at least 1 hour, stirring occasionally to develop flavor. Adjust seasoning as needed.
- Cook the Noodles: In large pots of boiling salted water, cook lasagna noodles according to package instructions until al dente. Drain and lay flat on parchment paper or lightly oiled trays to prevent sticking.
- Prepare the Ricotta Mixture: In a large mixing bowl, combine ricotta cheese, grated Parmesan, and a pinch of salt and pepper. Mix until smooth and well blended.
- Assemble the Lasagna: Use multiple large baking dishes or sheet pans (preferably 2-3), each approximately 18×24 inches. Spread a thin layer of meat sauce on the bottom of each dish. Layer noodles over the sauce, followed by a layer of ricotta mixture, shredded mozzarella, and more meat sauce. Repeat layers until ingredients are used, ending with a layer of noodles topped with meat sauce and cheese.
- Bake: Preheat the oven to 375°F (190°C). Cover each dish tightly with foil and bake for 45-50 minutes. Remove foil in the last 10 minutes to allow cheese to brown slightly. Check for doneness by ensuring the internal temperature reaches 165°F (74°C) or the cheese is bubbling and golden.
- Rest and Serve: Let the lasagna rest for at least 15 minutes before slicing and serving. This helps set the layers and makes serving easier.
Tips
- Scaling ingredients: Use large commercial-grade equipment where possible, and prepare ingredients in batches to streamline the process.
- Substitutions: For a vegetarian version, substitute the meat with sautéed vegetables like zucchini, mushrooms, and bell peppers. Use plant-based cheese if preferred.
- Storage: Cool the lasagna completely before refrigerating in airtight containers. It can be stored for up to 3 days in the fridge or frozen for up to 3 months.
- Common mistakes: Overcooking noodles can make them mushy; cook until just al dente. Also, avoid over-saucing to prevent soggy layers.
Serving Suggestions
Serve the lasagna hot, accompanied by a fresh green salad with vinaigrette and crusty bread or garlic bread for a complete meal. You can also add a side of roasted vegetables or a simple antipasto platter for variety.
Variations
For a different flavor profile, consider adding sautéed spinach or kale layers, or replacing beef with ground turkey or chicken. You can also make a white lasagna by substituting tomato sauce with béchamel sauce and adding cooked chicken or seafood.
Storage and Reheating
Allow the lasagna to cool completely before refrigerating. It can be stored in airtight containers for up to 3 days in the fridge. To reheat, cover with foil and warm in a preheated oven at 350°F (175°C) for 20-25 minutes, or until heated through. For larger portions, reheating in the oven preserves texture better than microwave, which can make cheese rubbery.
Frequently Asked Questions
Can I prepare this lasagna in advance?
Yes, you can assemble the lasagna a day ahead. Cover tightly and refrigerate. Bake it when ready, increasing the baking time by about 10-15 minutes to ensure it’s thoroughly heated.
What if I don’t have large baking dishes?
You can use multiple standard-sized pans or roasting trays. Just ensure they are oven-safe and can accommodate the layers comfortably. Alternatively, assemble in batches and serve separately.
How do I ensure even cooking in large quantities?
Use multiple oven racks and rotate the dishes halfway through baking. Cover dishes with foil to prevent over-browning, and check internal temperature to confirm doneness.
Is it necessary to pre-cook the noodles?
Yes, pre-cooking the noodles ensures they are tender and prevents a soggy or undercooked final dish. Use al dente noodles, as they will continue cooking slightly during baking.
How can I adapt this recipe for gluten-free guests?
Replace traditional lasagna noodles with gluten-free lasagna sheets or thinly sliced zucchini or eggplant as layers. Ensure all other ingredients, especially sauces and cheeses, are gluten-free.
What’s the best way to serve such a large lasagna at an event?
Use large, sturdy serving utensils and pre-cut the lasagna into portions before bringing it to the table. Keep it warm in the oven until serving time to maintain optimal temperature and texture.
