Ingredients

For the Zucchini Sauce

4 zucchini cut into medium cubes (roughly 2 lbs)
½ teaspoon kosher salt plus more to taste
4 tablespoon olive oil divided
2 teaspoon Tuscan seasoning
2 cloves garlic
2 cups fresh spinach
¼ cup grated parmesan cheese
½ cup ricotta
juice of 1 lemon plus more to taste

For the Pasta

1 pound pasta
Kosher salt
½ cup pasta water

To Serve

Basil
Parmesan Cheese
Lemon Zest
Red Pepper Flakes
Olive Oil

Instructions

Heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the zucchini and a pinch of salt and tuscan seasoning. Cook for about 10 minutes, stirring occasionally, until the zucchini is golden and caramelized. Add the spinach and let it wilt.
Stir in the garlic and cook for 30 seconds more. Remove from heat.
Transfer the zucchini mixture to a blender. Add the parmesan, ricotta, remaining 2 tablespoons of olive oil, and a squeeze of lemon. Blend until smooth. Taste and season with more salt if needed. Set aside.
Bring a large pot of salted water to a boil. Cook the pasta until al dente, reserving ½ cup of the pasta water. Drain and return the pasta to the pot.
Toss the pasta with the zucchini sauce, adding pasta water as needed until the sauce is creamy and coats the noodles evenly.
Serve immediately, topped with fresh basil, shaved parmesan, lemon zest, red pepper flakes, and a drizzle of olive oil.

Notes

Salt the zucchini before you cook it. Tossing the cubed zucchini with kosher salt and letting it sit for 10 minutes draws out excess moisture. Less water in the pan means faster caramelization and deeper flavor instead of steaming.
Do not rush the caramelization step. Those golden, slightly browned edges on the zucchini are where the flavor lives. The Maillard reaction concentrates the natural sugars in zucchini, giving the finished sauce a nutty, sweet depth that raw or barely cooked zucchini simply cannot deliver.
Add the garlic last in the saute, not first. Garlic burns fast, especially at medium-high heat. Stirring it in for just 30 seconds at the end of the zucchini cook keeps it fragrant and mellow rather than bitter and acrid.
Let the zucchini mixture cool for 2 minutes before blending. Hot liquids in a blender create steam pressure that can blow the lid off and burn you. A short rest before blending is a simple safety step that also prevents the ricotta from breaking under too much heat.
Blend the sauce longer than you think you need to. Zucchini has a fibrous cell structure that needs extra blending time to fully break down into a silky, smooth consistency. Stop too early and you get a chunky, uneven sauce instead of that lush, restaurant-quality texture.
Reserve your pasta water before you drain. Pasta water is loaded with dissolved starch from the cooking process, which acts as an emulsifier when added to the sauce. It helps the zucchini sauce cling to every noodle and creates a creamier, more cohesive final dish.
Cook your pasta to al dente, not fully soft. The pasta finishes cooking when you toss it with the warm sauce and hot pasta water in the pot. If it is already fully cooked when you drain it, the final toss will push it past the point of ideal texture into mushy territory.
Warm your sauce in the pasta pot before tossing. Cold or room-temperature sauce added to hot pasta drops the temperature of the whole dish instantly. Pouring the blended zucchini sauce back into the warm pasta pot for 30 seconds before tossing keeps everything at the right serving temperature.
Use pasta shapes with ridges or curves for this sauce. Rigatoni and casarecce have grooves and hollow interiors that trap creamy sauces. Smooth pasta like linguine lets this thick, blended sauce slide right off instead of coating every bite the way it should.
Add the lemon juice at the end of blending, not the beginning. Heat and prolonged blending can dull the brightness of fresh lemon juice. Squeezing it in right before you finish blending preserves the sharp, citrusy top note that keeps this sauce from tasting flat or heavy.
Finish each bowl with lemon zest, not just lemon juice. Lemon zest contains the essential oils from the peel, which deliver a more aromatic, floral citrus hit than juice alone. The combination of both juice in the sauce and zest on top creates a layered brightness throughout the whole dish.
Add the ricotta to the blender at room temperature. Cold ricotta does not blend as smoothly and can leave tiny white lumps in the sauce. Pulling it out of the fridge 15 minutes before you start cooking ensures it incorporates evenly into the blended zucchini mixture.
