Ingredients Section

Ingredients:

• 4 large yellow onions, thinly sliced (use high-quality onions for the best results)
• 3 tbsp olive oil or butter (I recommend using a good extra-virgin olive oil for depth)
• 1 tsp salt (adjust to taste)
• 1 tsp sugar (optional, for extra sweetness)
• 4 cloves garlic, minced (fresh garlic is best but feel free to use pre-minced for convenience)
• 1/2 tsp dried thyme
• 1/2 tsp dried rosemary (For a fresher taste, you can use fresh herbs, just double the amount)
• 1/4 cup vegetable broth (homemade or low-sodium store-bought works well)
• 1 lb pasta (spaghetti, fettuccine, or penne—your choice!)
• 1/2 cup Parmesan cheese, grated
• Fresh parsley, chopped (for garnish)
• Salt and pepper to taste

Prep Notes: Ensure your butter is at room temperature for easy mixing. If you’re in a rush, consider slicing those onions the night before and storing them in the fridge.

Brand Recommendations:

• Olive Oil: California Olive Ranch (extra-virgin)
• Parmesan Cheese: Grana Padano (for a great flavor that won’t break the bank)

Step-by-Step Instructions

1. Slice those onions: Thinly slice your onions and add them to the slow cooker. The thinner they are, the quicker they’ll caramelize.

2. Add the fats and seasonings: Add olive oil or butter to the slow cooker, along with the salt and optional sugar. Stir well to combine.

3. Let it cook: Cover the slow cooker and set it to low for 8-10 hours. Trust me, aim for the longer cook time if you can, as those onions really need the time to break down and sweeten.

4. Add the aromatics: About 30 minutes before the onions are done, add in your minced garlic, thyme, rosemary, and vegetable broth. Give it a gentle stir and let it continue cooking until aromatic.

5. Cook your pasta: When you’re ready to eat, boil the pasta according to package instructions. Remember to save a cup of that pasta water—this is gold for making your dish creamy!

6. Combine: Once the pasta is done, mix it gently with the caramelized onions, adding reserved pasta water little by little until you reach your desired creamy consistency.

7. Embellish: Stir in the grated Parmesan cheese, season with salt and pepper, and sprinkle with fresh parsley for a beautiful finish.

Chef’s Tip: If you’re looking for a vegan dish, the nutritional yeast will lend a similar umami kick when stirred in at the end.

Expert Tips & Tricks

Creating the perfect slow-cooked caramelized onions doesn’t have to be intimidating, so I’ve rounded up some essential tips for amazing results:

• Make-Ahead: You can slice the onions and store them in the fridge a day before you plan on cooking. Just toss them in the slow cooker when you’re ready.
