Bring a large pot of salted water to a boil. Wash and dry produce.

Trim and halve zucchini lengthwise; slice crosswise into ½-inch-thick half-moons. Zest and quarter lemon. Peel and finely chop garlic. Finely chop parsley.

Melt 1 TBSP butter (2 TBSP for 4 servings) in a large pan over medium-high heat. Add panko; season with salt and pepper. Cook, stirring, until golden brown, 3-4 minutes.

Turn off heat; transfer to a small bowl. Wipe out pan.

Heat a drizzle of oil in same pan over medium heat. Add zucchini and season with salt and pepper. Cook, stirring occasionally, until softened, 2-3 minutes.

Turn off heat. Sprinkle with half the lemon zest, then transfer to a plate. Wipe out pan.

Heat a drizzle of oil in same pan over medium-high heat. Add sausage* and cook, breaking up meat into pieces, until browned and cooked through, 4-6 minutes. Transfer to a plate.

Once water is boiling, gently add ravioli to pot. Reduce to a low simmer. Cook, stirring occasionally, until tender and floating to the top, 3-4 minutes.

Reserve ½ cup pasta cooking water (1 cup for 4 servings), then drain and set aside.

Meanwhile, melt 1 TBSP butter (2 TBSP for 4 servings) in pan used for zucchini over medium-high heat. Add garlic, tomato paste, and half the Italian Seasoning (all for 4). Cook, stirring, until fragrant, 1-2 minutes.

Whisk in crème fraîche, cream cheese, stock concentrate, and ¼ cup reserved pasta cooking water (½ cup for 4) until melted and combined.

Stir in ¼ tsp sugar (½ tsp for 4); season with salt and pepper.

Add a squeeze of lemon juice and remaining lemon zest to taste. Simmer until sauce has thickened slightly, 1-2 minutes more.

Gently stir drained ravioli into pan with sauce. Season with salt and pepper. TIP: If needed, stir in more reserved pasta cooking water a splash at a time until ravioli are coated in a creamy sauce.

Divide between bowls. Top with zucchini, toasted panko, and parsley. Serve.
