Equipment

  • Large pot for boiling pasta
  • Large Skillet or Sauté Pan: For cooking vegetables and preparing the sauce.
  • Saucepan: (Optional) For warming the cream separately.
  • Whisk: To blend the sauce smoothly.

Ingredients
  

  • For the Pasta & Vegetables:
  • 8 oz fettuccine pasta or your favorite pasta
  • 1 cup broccoli florets
  • 1 cup sliced mushrooms cremini or white button work well
  • 2 cups fresh spinach roughly chopped
  • ½ cup peas fresh or frozen; if frozen, thaw before using
  • Salt: For pasta water
  • For the Alfredo Sauce:
  • 2 tablespoons unsalted butter
  • 3 garlic cloves minced
  • 1 cup heavy cream you can substitute half-and-half for a lighter version
  • 1 cup freshly grated Parmesan cheese
  • Salt and black pepper to taste
  • Optional Garnish: Chopped fresh parsley

Instructions
 

  • Cook the Pasta:
  • Bring a large pot of salted water to a boil.
  • Add the fettuccine and cook according to package directions until al dente.
  • Reserve about ½ cup of pasta water, then drain the pasta and set aside.
  • Sauté the Vegetables:
  • While the pasta cooks, heat 1 tablespoon of butter in a large skillet over medium heat.
  • Add the broccoli and mushrooms. Sauté for about 4–5 minutes until they start to soften.
  • Stir in the peas and spinach, cooking for an additional 2 minutes until the spinach wilts.
  • Remove the vegetables from the skillet and set aside. (They will be mixed back into the dish later.)
  • Prepare the Alfredo Sauce:
  • In the same skillet (wipe it clean if needed), melt the remaining 1 tablespoon of butter over medium heat.
  • Add the minced garlic and sauté for about 1 minute until fragrant—avoid browning the garlic.
  • Pour in the heavy cream and let it simmer gently for 3–4 minutes, stirring frequently.
  • Gradually whisk in the grated Parmesan cheese until the sauce is smooth and creamy.
  • Season with salt and freshly ground black pepper. If the sauce seems too thick, add a splash of the reserved pasta water to loosen it.
  • Combine & Serve:
  • Add the drained pasta and sautéed vegetables back into the skillet with the Alfredo sauce.
  • Toss gently to ensure everything is well coated. Warm everything together for an extra 1–2 minutes over low heat.
  • Taste and adjust seasoning if needed.
  • Serve hot, garnished with chopped parsley and extra Parmesan on top if desired.

Notes

Vegetable Variations: Feel free to swap or add any of your favorite vegetables (such as bell peppers or zucchini) to customize the dish.
Pasta Choices: Although fettuccine is traditional, you can use any pasta you enjoy.
Creaminess Adjustment: For a lighter version, try using half-and-half instead of heavy cream; just note the sauce may be slightly less rich.
Vegan Option: To adapt this recipe for a vegan diet, substitute dairy ingredients with plant-based alternatives (e.g., use vegan butter, cashew cream or coconut cream, and nutritional yeast in place of Parmesan cheese).
Consistency Tip: If the sauce becomes too thick, gradually add a little more pasta water until your desired consistency is reached.
