Step 1: Cook the Pasta
Boil Water: Bring a large pot of salted water to a boil.
Cook the Pasta: Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of pasta water before draining.
Drain and Set Aside: Drain the pasta in a colander and set it aside.
Step 2: Sauté the Aromatics
Heat Oil: In a large skillet, heat the olive oil over medium heat.
Add Onions and Garlic: Sauté the chopped onion until translucent, about 5 minutes. Add the minced garlic and cook for an additional minute until fragrant.
Step 3: Add the Cavolo Nero
Incorporate the Greens: Add the chopped cavolo nero (or kale) to the skillet. Cook for about 5-7 minutes, stirring occasionally, until the leaves are tender and wilted.
Pour in the Broth: Add the vegetable broth and bring the mixture to a simmer. Allow it to cook for another 5 minutes.
Step 4: Combine with Pasta
Mix Everything Together: Add the drained pasta to the skillet. If it seems dry, gradually add some reserved pasta water until the desired consistency is reached.
Season: Season with salt, pepper, and red pepper flakes (if using). Toss everything to combine well.
Step 5: Serve
Garnish: Serve the pasta hot, topped with grated Parmesan cheese and fresh herbs. Enjoy.
