Part 2/7:
Once the water is boiling, carefully add the lasagna noodles, ensuring they remain al dente. This means they should retain a slight firmness, as they will continue to cook in the oven and absorb flavors. After cooking for about 5 minutes, drain the noodles and rinse them with cold water to halt the cooking process and prevent them from sticking together.
Preparing the Cream Sauce
While the noodles are cooking, it’s the perfect time to focus on the prep work. Finely dice a large onion and mince four garlic cloves. In a large skillet over medium heat, melt 1/4 cup of butter, then add the diced onion and minced garlic to cook for about 3 minutes until soft and aromatic.
