1. In a large skillet over medium-high heat, brown the ground beef and Italian sausage, breaking up the meat as it cooks. Drain excess fat if needed.

2. Add butter to the skillet. Once melted, stir in minced garlic and sauté for 1–2 minutes until fragrant.

3. Reduce heat to medium-low and pour in the heavy cream. Stir in parmesan cheese and let it simmer until slightly thickened.

4. Add spinach and stir until wilted but still vibrant in color.

5. Meanwhile, cook the penne pasta in salted boiling water until al dente. Drain and reserve a bit of pasta water.

6. Add the cooked pasta to the sauce and meat mixture. Stir to coat evenly. Add a splash of reserved pasta water if needed to loosen the sauce.

7. Transfer to a baking dish, sprinkle mozzarella over the top, and broil for 2–3 minutes until bubbly and golden.

8. Serve immediately and enjoy!
