Ingredients
- 4 large yellow onions, thinly sliced (Opt for fresh, preferably organic onions for the best flavor.)
- 3 tbsp olive oil or butter (Use high-quality extra virgin olive oil for an added punch of flavor or go with unsalted butter for richness.)
- 1 tsp salt (I recommend kosher salt; it dissolves nicely and provides a uniform flavor.)
- 1 tsp sugar (optional for extra sweetness; this can enhance the caramelization process.)
- 4 cloves garlic, minced (Fresh garlic is best here. Feel free to adjust based on your preference.)
- 1/2 tsp dried thyme (You can replace with fresh thyme if you have it on hand.)
- 1/2 tsp dried rosemary (Again, fresh is fantastic if you have it. Fresh herbs tend to have a bolder flavor.)
- 1/4 cup vegetable broth (Help soften those onions during cooking, elevating the dish.)
- 1 lb pasta (Choose from spaghetti, fettuccine, or penne—whatever you love!)
- 1/2 cup Parmesan cheese, grated (Use fresh Parmesan for optimal flavor; the pre-grated stuff doesn’t compare!)
- Fresh parsley, chopped (for garnish)
- Salt and pepper to taste
Prep Notes:
- Ensure your butter is at room temperature for easy mixing.
- For the best flavor, slice your onions evenly and think about investing in a good-quality mandoline to save time.
Step-by-Step Instructions
Thinly slice onions and add to the slow cooker.
- Ensure the slices are uniform; this will help them cook evenly.
Add olive oil or butter, salt, and optional sugar. Stir well, cover, and cook on low for 8-10 hours.
- You want those onions to become soft and start to develop color. The longer you leave them, the richer the flavor!
30 minutes before completion, add minced garlic, thyme, rosemary, and vegetable broth.
- This prevents the garlic from burning. Stir it all together and cover again until done.
Boil the pasta per package instructions, reserving a cup of pasta water.
- This starchy water will help create a creamy sauce. Don’t skip this step!
Mix the pasta with caramelized onions, adding reserved water as needed for a creamy consistency.
- The key is to start with a little water and add more as needed until you reach your desired creaminess.
Stir in Parmesan cheese, season with salt and pepper, and garnish with fresh parsley.
- Taste and adjust the seasoning. This is your chance to make it just right!
Chef’s Tips:
- For a bit of a kick, add red pepper flakes to the onions when you mix in the garlic.
- Common mistake: Make sure to keep the lid on your slow cooker during the cooking process to retain steam and moisture!
