What You’ll Need

2 garlic cloves, peeled and smashed
3/4 cup extra virgin olive oil
Pinch of crushed red pepper flakes (adjust according to your spice preference)
1 pound kale, ribs removed and leaves chopped
1/2 pound rigatoni (or any other pasta you prefer)
Zest of 1 lemon
1 teaspoon fresh lemon juice, plus more to taste
1/3 cup freshly grated Parmesan cheese, plus extra for sprinkling
Freshly ground black pepper, for serving

Cook’s Kit

Large pot for boiling pasta
Large skillet or sauté pan
Colander or strainer
Microplane or fine grater (for lemon zest and Parmesan)
Knife and cutting board
Wooden spoon or spatula
Citrus juicer or reamer (optional, for lemon juice)

Method: Rigatoni with Easy Kale Sauce

Step 1: Cook the Rigatoni

Bring a large pot of salted water to a rolling boil. Add the rigatoni and cook according to package instructions until al dente. Reserve about 1 cup of the pasta cooking water before draining. This starchy water will help create a silky sauce later. Drain the pasta and set aside.

Step 2: Prepare the Kale Sauce

While the pasta cooks, heat the extra virgin olive oil in a large skillet over medium heat. Add the smashed garlic cloves and a pinch of crushed red pepper flakes. Sauté gently for 1-2 minutes until the garlic is fragrant and just beginning to turn golden—be careful not to burn it.

Step 3: Wilt the Kale

Add the chopped kale to the skillet. Stir to coat the leaves in the garlic oil, then cover and cook for 3-4 minutes, stirring occasionally, until the kale is tender and wilted.

Step 4: Blend the Sauce

Remove the garlic cloves from the skillet. Transfer the kale and olive oil mixture to a food processor or blender. Add the lemon zest, 1 teaspoon fresh lemon juice, and the grated Parmesan cheese. Blend until smooth, adding reserved pasta water a few tablespoons at a time to reach your desired sauce consistency. The sauce should be creamy and easy to toss with pasta.

Step 5: Combine and Serve

Return the sauce to the skillet and add the cooked rigatoni. Toss well to coat every piece in the luscious kale sauce. Adjust seasoning with more lemon juice, salt, and freshly ground black pepper to taste. Serve hot with an extra sprinkle of Parmesan on top.

Nutrition-Minded Tweaks

Use whole wheat or legume-based rigatoni for added fiber and protein.
Reduce the amount of olive oil slightly if you want a lighter sauce.
Add toasted pine nuts or walnuts for a dose of healthy fats and crunch.
Incorporate a handful of fresh herbs like basil or parsley for extra antioxidants.
Swap Parmesan for a plant-based cheese alternative to make it dairy-free.

Pro Tips & Notes

Garlic: Smashing the garlic cloves instead of mincing helps infuse the oil gently and allows you to remove them easily before blending.
Pasta Water: Don’t skip reserving the pasta water—it’s the secret to a silky sauce that clings beautifully to the rigatoni.
Kale Prep: Removing the tough ribs from kale ensures a smooth sauce without any fibrous bits.
Adjust Spice: The crushed red pepper flakes add subtle heat; customize to your liking or omit for a milder version.

Meal Prep & Storage Notes

This Rigatoni with Easy Kale Sauce holds up well for leftovers. Store any cooled pasta in an airtight container in the refrigerator for up to 3 days. When reheating, add a splash of water or olive oil and warm gently on the stove or in the microwave to loosen the sauce and keep it creamy.

For meal prep, prepare the kale sauce ahead of time and keep it refrigerated separately. Cook the rigatoni fresh or store cooked pasta with a little olive oil to prevent sticking. Combine and reheat when ready to serve for a quick, nutritious meal.

Helpful Q&A

Can I use other greens instead of kale for the sauce?

Absolutely! Spinach, Swiss chard, or even collard greens work beautifully. Just be sure to adjust cooking times as some greens wilt faster than kale.

Is it necessary to use lemon zest and juice?

The lemon zest and juice brighten the sauce, balancing the earthy kale and rich olive oil. You can omit or reduce if you prefer a less tangy flavor, but it really elevates the dish.

Can I make this recipe vegan?

Yes! Simply substitute the Parmesan cheese with a vegan cheese alternative or nutritional yeast for a cheesy flavor without dairy.

What pasta shapes work best with this sauce?

Rigatoni is ideal because its ridges and tube shape hold the sauce well, but penne, fusilli, or even Chicken Bolognese With Rigatoni style pasta also pair wonderfully.
