Instructions
- 1
Bring a large pot of salted water to a rolling boil and add the whole wheat pasta, cooking until al dente (about 9-11 minutes), then drain while reserving ½ cup of the starchy cooking liquid.
- 2
Heat 2 tablespoons of olive oil in a large skillet over medium heat, add the sliced mushrooms, and sauté for 4-5 minutes until they soften and their moisture evaporates.
- 3
Add the minced garlic to the mushroom mixture and cook for about 1 minute, stirring frequently, until fragrant and lightly toasted.
- 4
Reduce the heat to medium-low, add the 2 tablespoons of butter, and allow it to melt completely into the garlic and mushroom base.
- 5
Dust the flour over the mixture and whisk for 2 minutes to create a light roux that coats the vegetables.
- 6
Slowly pour in the whole milk while whisking constantly to ensure no lumps form, then add the Greek yogurt in small spoonfuls while stirring gently.
- 7
Let the sauce simmer on medium-low heat for 3-4 minutes, stirring occasionally, until it reaches a silky consistency that lightly coats the back of a spoon.
- 8
Stir in the sea salt, black pepper, and nutmeg, then taste and adjust seasonings to your preference.
- 9
Fold the chopped spinach into the warm sauce and stir for 1-2 minutes until completely wilted and tender.
- 10
Remove from heat and gradually stir in the grated Parmigiano-Reggiano cheese until smooth and fully incorporated.
- 11
Add the cooked pasta to the skillet and toss gently to coat all the noodles, adding reserved pasta water 1-2 tablespoons at a time if the sauce appears too thick.
- 12
Divide among serving bowls or plates and finish with a sprinkle of fresh parsley and additional cheese if desired.
