Slow Cooker Spinach Pasta Primavera

Ingredients:

Step-by-Step Directions:

Step 1: Prep the Slow Cooker: Lightly grease the inside of a 4- / to 6- / quart slow cooker with a splash of olive oil or nonstick cooking spray to help prevent the starchy pasta from sticking stubbornly to the sides of the liner.

Step 2: Layer the Vegetable Aromatics: Add the chopped yellow onion, broccoli florets, sliced carrots, sliced bell peppers, frozen peas, and halved cherry tomatoes straight into the bottom of the slow cooker. Drizzle the vegetables evenly with the 2 / tablespoons of olive oil or melted butter, then sprinkle the minced garlic, Italian seasoning, dried basil, salt, black pepper, and optional red pepper flakes across the top.

Step 3: Add the Pasta Layer: Pour your 8 ounces of uncooked short pasta evenly over the top of the seasoned vegetables. Do not stir the pot yet!

A Friendly Kitchen Note: Keeping the dry pasta sitting cleanly on top of the vegetables at this stage is the ultimate secret to success. It allows the pasta to cook evenly via rising steam rather than boiling too rapidly at the bottom of the pot, which prevents the noodles from breaking down into a mushy texture.

Step 4: Whisk the Creamy Sauce Base: In a medium mixing bowl, whisk together the vegetable broth and heavy cream (or half-and-half). Stir in exactly 3/4 / cup of the grated Parmesan cheese until it is mostly dissolved. Slowly pour this liquid mixture evenly over the pasta and vegetables in the slow cooker, making sure the pasta is just barely submerged. If needed, use the back of a large spoon to lightly press the dry noodles down into the liquid, but continue to avoid stirring the layers together.

Step 5: The Low and Slow Simmer: Secure the lid onto your slow cooker and cook on LOW for 2 1/2 / to 3 / hours until the pasta is just tender. Because every slow cooker has its own unique heating personality, begin checking the noodle texture around the 2-hour mark. Give the mixture a very gentle stir when you check it to help redistribute the liquid and ensure even cooking.

Step 6: Wilt the Spinach and Meltdown: Once the pasta reaches a perfect, tender bite, drop in the fresh baby spinach by the handful, gently folding it into the piping hot pasta and cream sauce. The residual ambient heat will wilt the greens completely within a minute or two. If the sauce looks a bit too thick or dry, simply stir in an extra splash of broth or cream to loosen it up.

Step 7: Flavor Calibration and Service: Taste the cream sauce and add an extra pinch of salt and pepper if desired. Scatter the remaining 1/4 / cup of Parmesan cheese uniformly over the top, pop the lid back on, and let the pot sit on WARM or LOW for an additional 5 / to 10 / minutes to allow the flavors to meld. Spoon the vibrant pasta into warm bowls, garnish with fresh parsley, and serve right away while the texture is at its peak!
