Bring a large pot or dutch oven to medium-high heat. Once hot, add ground beef. If you're using ground beef that's super lean, you will need to add a bit of oil to the pan first. Season with kosher salt & black pepper, then break apart with your spatula, and continue cooking until browned through. Pour out any excess grease.
1 lb ground beef, kosher salt & black pepper
Reduce heat to medium, then add in the yellow onion and sauté, stirring occasionally, for 3-4 minutes, until starting to turn translucent. Add in the garlic, stir, and cook for 30 more seconds. Then, add in the tomato paste, zucchini, italian seasoning & red pepper flakes. Stir and let cook for 2 more minutes.
1 small yellow onion, 4-6 garlic cloves, 2 tbsp tomato paste, 2 tsp italian seasoning, red pepper flakes, 2 small zucchinis
Delgaze the pot with broth, scraping up any browned bits at the bottom. Then, add in the marinara sauce, stir, increase heat and bring the soup up to a boil. Once boiling, add in the broken-up lasagna noodles, reduce the heat to low and let simmer until al-dente, about 10-12 minutes, stirring occasionally.
6 cups beef or chicken broth, 1 jar marinara sauce, 8 oz lasagna noodles
Meanwhile, in a medium bowl mix together all of the ricotta topping ingredients with a spoon or spatula until combined. Set aside.
1 cup ricotta cheese, ½ cup finely shredded low-moisture, part-skim mozzarella cheese, ¼ cup finely grated parmesan cheese, 2 tbsp fresh chopped basil, 1 garlic clove, kosher salt & black pepper
Taste the soup and adjust the amount of kosher salt, black pepper & red pepper flakes as needed. Then, top each bowl with a scoop or two of the ricotta mixture and more fresh basil and grated parmesan as desired. Enjoy!
