Preheat oven to 350°F.

Cut the kabocha squash in half width wise (not through the stem). Scoop out and discard the seeds, strings, and all other nasty bits. Pour a thin layer of water (about ¼ cup) into a baking dish and place the squash halves cut side down in the water. Bake the squash until it is fork tender (an inserted fork goes in and out with ease, about 45 minutes). Once the squash is cool enough to handle, scoop out the flesh from the skins and transfer to a food processor or blender. Puree until smooth. Discard the skins.

Fill a large pot with water and bring to a boil over high heat. Once boiling, add a good handful of kosher salt (about 2 tablespoons). Add the whole wheat spaghetti, reduce the heat to low and simmer uncovered until pasta is al dente, stirring occasionally.*

Prepare the sauce while the pasta is cooking. In a large frying pan, warm olive oil over medium heat. Add the shallots and sauté until soft (4 – 5 minutes). Stir in the kabocha squash puree and cook for an additional minute. Add the cream 1 tablespoon at a time. With each addition, slowly stir the cream into the squash mixture making sure it is completely incorporated before the next addition. Add the Parmesan cheese and nutmeg, stirring to incorporate. Stir in low sodium chicken stock until the consistency of the sauce is smooth and somewhat thin (we will be adding some pasta cooking water later, so don’t completely thin out the sauce).

Once the spaghetti is ready, drain, but reserve 2 cups of the cooking liquid in a separate bowl or measuring cup. Return the spaghetti to the pot it was cooked in.

In small amounts, add some of the cooking liquid to the sauce until desired consistency is achieved. Remove the sauce from the heat and add parsley and lemon juice. Taste your sauce and season with salt, pepper and additional lemon juice if needed. Add several large spoonfuls of the sauce to the spaghetti, tossing until the spaghetti is evenly coated.

Divide spaghetti between four dinner plates. Top each serving with a healthy spoonful of sauce, additional Parmesan cheese and freshly ground pepper. Garnish with whole parsley leaves.
