Instructions

  1. Bring a large pot of salted water to a boil. Add agnolotti and cook according to package directions until tender. Reserve 1/2 cup pasta water before draining.
  2. While pasta cooks, heat olive oil in a large skillet over medium heat. Add onion and cook, stirring, until softened, about 3 minutes. Add garlic and cook 30 seconds more.
  3. Add kale to the skillet and cook, tossing, until wilted, about 2 minutes. Season with salt and pepper. Transfer kale mixture to a plate.
  4. In the same skillet, melt 1 tablespoon butter and garlic herb butter over medium heat. Add sage leaves and cook until butter turns golden brown and smells nutty, about 2 minutes. Be careful not to burn.
  5. Add cooked agnolotti and kale mixture to the skillet with the brown butter. Toss gently to coat, adding a splash of reserved pasta water if needed to loosen the sauce.
  6. Divide among plates. Top with Parmesan cheese and chopped walnuts. Serve immediately.

Recipe Tips

For the best brown butter, watch the butter closely as it foams and turns a light amber color-it can go from perfect to burnt quickly.

If you can’t find garlic herb butter, substitute with 2 tablespoons regular butter plus 1/4 teaspoon garlic powder and 1/2 teaspoon dried mixed herbs.

To make this dish vegetarian, ensure the agnolotti and Parmesan are made with vegetarian rennet.

FAQ

Can I use frozen agnolotti instead of fresh?

Yes, frozen agnolotti work well. Cook them according to package directions, usually a minute or two longer than fresh.

What can I substitute for kale?

Swiss chard, spinach or beet greens are good substitutes. If using spinach, add it at the very end and cook just until wilted.

How do I store leftovers?

Store in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet with a splash of water or broth to refresh the sauce.
