Ingredients You'll Need

To embark on this culinary journey and create an unforgettable **slow cooker fettuccine alfredo recipe**, gather these simple ingredients:

1 lb (450g) fettuccine pasta, broken in half
4 cups (960ml) chicken or vegetable broth
1 tbsp (15ml) olive oil
2 cloves garlic, minced
1/2 cup (120ml) heavy cream
1/2 cup (120ml) milk (whole milk recommended)
1/2 cup (113g) unsalted butter, cut into cubes
1 cup (100g) freshly grated Parmesan cheese, plus more for serving
1/2 tsp salt
1/4 tsp black pepper
Fresh parsley, chopped, for garnish (optional)

Step-by-Step Instructions

Follow these straightforward steps to prepare your amazing **slow cooker fettuccine alfredo recipe**:

Prepare the Slow Cooker: Lightly grease the inside of your slow cooker crock with a little olive oil or non-stick spray.
Combine Liquids & Aromatics: In the slow cooker, combine the chicken or vegetable broth, olive oil, minced garlic, heavy cream, milk, butter, salt, and pepper. Whisk gently until mostly combined.
Add Pasta: Add the broken fettuccine pasta to the slow cooker. Gently push the pasta down into the liquid to ensure it's mostly submerged. Do not stir too vigorously at this point, as it can make the pasta stick together.
Cook: Cover and cook on HIGH for 2-2.5 hours, or on LOW for 3.5-4 hours. The cooking time may vary slightly depending on your slow cooker. The pasta should be tender but still have a slight bite (al dente).
Stir in Cheese: Once the pasta is cooked, remove the lid. Add the grated Parmesan cheese and stir vigorously until the cheese is fully melted and the sauce is smooth and creamy. The heat from the pasta and the remaining liquid will melt the cheese beautifully.
Serve: Ladle the creamy Fettuccine Alfredo into bowls, garnish with fresh parsley and extra Parmesan cheese if desired, and serve immediately.

Tips for the Perfect Alfredo

To ensure your Alfredo turns out perfectly every time, consider these helpful tips:

Freshly Grated Parmesan: Avoid pre-grated cheese, as it often contains anti-caking agents that can make your sauce gritty. Freshly grated Parmesan melts more smoothly and tastes superior.
Adjust Consistency: If the sauce is too thick, add a splash more warm milk or broth until it reaches your desired consistency. If it's too thin, let it sit for a few minutes; it will thicken as it cools.
Don't Overcook Pasta: Keep an eye on the pasta towards the end of the cooking time. Overcooked pasta can become mushy.
Add Protein: For a heartier meal, stir in cooked chicken, shrimp, or even some sautéed mushrooms during the last 30 minutes of cooking, or just before serving.

Nutritional Notes & Customization

While classic Alfredo is rich, you can make minor adjustments. Opt for low-sodium broth to reduce sodium intake. You can also incorporate a handful of spinach or finely chopped broccoli during the last 20 minutes of cooking for added nutrients and color. This simple **slow cooker fettuccine alfredo recipe** offers a satisfying meal that can be enjoyed as a comforting indulgence or adapted to fit dietary preferences.
