This is the recipe that my mother made when I was growing up. It is not authentic in many ways, but it is delicious comfort food using ingredients that were readily available in a grocery store in the 1970s.
Heat oil in a large skillet over medium high heat. Saute onion until tender.
Add ground beef, cook until browned.
Mash garlic with salt and add to meat with pepper, oregano, parsley, tomatoes, and tomato sauce. Simmer for 30 minutes.
If making ahead, refrigerate sauce until ready to assemble.
Cook lasagne noodles until al dente. Drain & cover with cold water.
Spread ⅓ of sauce in a 9×13 pan. Top with half each of lasagne noodles, Swiss cheese (reserve 1 slice) & cottage cheese.
Repeat, ending with remaining sauce and reserved cheese.
Bake for 30 minutes or until hot & bubbly.
You can substitute mozzarella for the Swiss cheese and ricotta for the cottage cheese for a more authentic dish.
