Ingredients

• 4 large yellow onions (thinly sliced)
• 3 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon dried thyme
• 1/4 cup dry white wine (optional)
• 12 oz pasta (fettuccine, linguine, or your favorite shape)
• 1/2 cup grated Parmesan cheese
• 1/2 cup heavy cream (optional, for a creamy version)
• Fresh parsley (chopped, for garnish)

Instructions

Step 1: Caramelize the Onions

1. Add the sliced onions to the slow cooker. Top with the unsalted butter, olive oil, salt, black pepper, and dried thyme.
2. Cover and cook on low for 8-10 hours, stirring occasionally, until the onions are deeply caramelized and golden brown.
3. If using, add the white wine during the last hour of cooking to deglaze the onions and add extra depth of flavor.

Step 2: Cook the Pasta

1. When the onions are nearly ready, bring a large pot of salted water to a boil. Cook the pasta according to the package instructions until al dente. Drain and set aside.

Step 3: Combine Pasta and Caramelized Onions

1. Add the cooked pasta to the slow cooker with the caramelized onions. Toss to combine until the pasta is evenly coated with the onions.
2. Stir in the grated Parmesan cheese and heavy cream (if using) for a creamy version.

Step 4: Serve

• Serve the caramelized onion pasta warm, garnished with chopped fresh parsley and extra Parmesan cheese if desired. Pair with a side salad or crusty bread for a complete meal.

Cooking Notes

• Onion Choice: Yellow onions work best for this recipe because they become sweet and caramelize beautifully. You can also use a mix of yellow and red onions for added color and flavor.
• White Wine: Adding white wine is optional but adds a lovely depth to the caramelized onions. You can substitute with vegetable broth if you prefer.
• Pasta Water: Reserve some pasta cooking water before draining to help loosen the sauce if needed when mixing the pasta with the onions.

Variations

Creamy Caramelized Onion Pasta

• Add 1/2 cup heavy cream and 1/4 teaspoon nutmeg to the pasta for a rich, creamy version of this dish.

Caramelized Onion and Mushroom Pasta

• Add 8 oz of sliced mushrooms to the slow cooker during the last 2 hours of cooking for an earthy addition that pairs perfectly with the onions.

Caramelized Onion and Bacon Pasta

• Cook 4-6 slices of bacon until crispy. Crumble the bacon and stir it into the pasta just before serving for a smoky, savory twist.
