6 servings; MFP. Watch so it doesn't burn. Maybe boil noodles a bit so they are done before it burns.
Biggest SS pan (9 x 11.75) worked well for the recipe below. This is HALF the original 12 servings recipe:

1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
325 g/0.5 jar spaghetti sauce
1 1/4 cup tomato sauce (50/50 tomato paste/water)
212 g/4 ounces whole-milk ricotta cheese (about 1 cup)
170 g/6 oz shredded mozzarella cheese
30 g/2 oz grated Parmesan cheese (about 1 packed cup)
400F; Soak broken up noodles in hot water (STIR so they don't stick).
Cook veggies, meat, spices.
Add in drained noodles and sauce; stir and add to baking pan.
Cover with ricotta dollops, parm, and mozz (in that order)
Baked uncovered 30-35 mins.
Original recipe:
Heat the oven to 400ºF. Coat an 18x13-inch rimmed baking sheet (half sheet pan) with cooking spray. Break 1 (16-ounce) box dried lasagna noodles into rough 2 to 3-inch pieces and place in a large bowl, then add enough warm water to cover by an inch or so.
Heat 1 tablespoon olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat until shimmering. Add 1 diced medium yellow onion and cook, stirring occasionally, until translucent and lightly browned, 4 to 5 minutes. Stir in 3 minced garlic cloves and cook until fragrant, about 1 minute.
Add 1 pound ground beef, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Use a wooden spoon to break the beef up into small pieces and cook, stirring occasionally, until the beef is browned and cooked through, about 5 minutes.
Drain the noodles. Add the noodles and 2 (about 24-ounce) jars marinara sauce to the pot and stir to combine.
Transfer to the baking sheet and spread into an even layer, making sure all the noodles are covered with a layer of sauce. Using a spoon, dollop 8 ounces ricotta cheese evenly over the noodles. Sprinkle with 8 ounces shredded mozzarella cheese and 4 ounces grated Parmesan cheese.
Bake uncovered until the noodles are tender and the cheeses are melted and browned, 30 to 35 minutes.
