Ingredients
1 tablespoon olive oil
1 yellow onion, diced
6 cloves garlic, thinly sliced
1.5 tablespoons Italian seasoning
2 tablespoons tomato paste
1/2 cup basil pesto
1/2 cup uncooked split red lentils
2 (28 oz) cans fire-roasted crushed tomatoes
4 cups vegetable broth
1–2 teaspoons granulated sugar (optional)
8 uncooked lasagna noodles, broken into bite-sized pieces
2–3 cups chopped fresh baby spinach (optional)
1/2 cup Parmesan cheese
1/2 cup shredded mozzarella cheese
1 cup whole milk ricotta cheese
Kosher salt, to taste
Fresh cracked black pepper, to taste
Fresh chopped parsley, for garnish
Instructions
In a large pot over medium-high heat, heat olive oil. Add onion and a pinch of salt and pepper; sauté ~3 minutes.
Reduce heat to medium. Add garlic, Italian seasoning, and more salt/pepper. Sauté for 1 minute.
Stir in tomato paste and cook ~2 minutes, until it deepens in color.
Deglaze the pot with a splash of vegetable broth. Stir in pesto, red lentils, crushed tomatoes, remaining broth, and sugar (if using).
Bring to a gentle simmer over medium-high heat, stirring occasionally to prevent sticking.
Stir in broken lasagna noodles. Reduce heat to low and simmer 12–15 minutes, until noodles are al dente. Stir occasionally.
Remove from heat. Stir in spinach until wilted. Season with additional salt and pepper to taste.
Serve topped with Parmesan, mozzarella, and a dollop of ricotta. Cover pot briefly to allow cheese to melt. Garnish with parsley.
Notes
Tomato Alternatives: Use puree, canned tomato sauce, or jarred marinara for a smoother texture.
Pasta Substitutions: Any pasta shape will work—try penne, rotini, rigatoni, or even bowties.
Greens Tip: Swap spinach with kale, chard, arugula, or mustard greens—great for using up older greens!
Make Ahead: This soup reheats well and makes a great leftover or meal prep option.
