Cook onion in a little oil, I used olive oil. Once the onion is translucent, add garlic. Cook for a couple minutes.
Add meat of choice to the onion.
Cook the meat. Add the salt, pepper, garlic powder, onion powder, and Italian seasoning. Add your sauce. I typically get the great value marinara.
Prep your noodles. I broke my pasta up into smaller pieces.
Cook your noodles if needed. This will depend on your noodles you are using. There are quite a few low carb options on Amazon. Add to your sauce when they are ready.
Add cheese. I used 1 1/2 cup Italian cheese and 1/2 c parmesan.
Once mixed, pour onto the sheet pan. I didn't spray mine, but you might need to.
In a bowl add ricotta cheese, 1/2 cup parmesan cheese and about 1/2 cup of mozzarella or other cheese. I add Italian seasoning to the ricotta. If adding spinach or a veggie, add now. Stir.
Dollop on top of the lasagna on the sheet pan.
Sprinkle with more cheese if desired. I worked on making it cheesy but not too much cheese.
Bake at 350 degrees for 15-30 minutes. If you like your lasagna a bit crispy, bake it longer. I baked ours until bubbly but not too brown.
Serve as desired. I just used a Caeser salad kit.
