Preheat oven to 425 degrees.
Cook pasta al dente according to package directions. Save 1/2 cup of water.
To prepare the sauce, bring a large skillet to medium-high heat. Add in the oil and sauté the diced onions for 2-3 minutes. Add in the meat and break it up really well to avoid any clumps. Cook until the meat it no longer pink.
Add in the spaghetti sauce, tomato paste, salt, spices and pasta water. Cook until the sauce thickens up. About 5-7 minutes. Remove from heat.
To assemble the lasagna, place about 1 cup of the pasta sauce on the bottom of a 9 x 13 inch baking dish. Then cover the sauce by laying 3 sheets of the lasagna pasta. Spread some ricotta cheese, add more meat sauce, mozzarella cheese and some fresh basil. Repeat the steps until you run out of the ingredients. You should have about 4 layers total.
Cover with foil wrap and bake for 20 minutes. Then remove the foil wrap and bake for another 10 minutes.
Once the cook time is done, remove from the oven, let it rest for about 5 minutes, then garnish with fresh basil and serve.
