Ingredients

Scale

3 large yellow onions, thinly sliced
3 tablespoons olive oil
4 cloves garlic, minced
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried thyme
12 ounces dry spaghetti pasta
4 cups vegetable broth
1 cup water
1/2 cup grated Parmesan cheese
2 tablespoons unsalted butter
1/4 cup chopped fresh parsley

Instructions

Heat the olive oil in a large deep skillet or wide pot over medium heat.
Add the sliced onions and 1/2 teaspoon salt. Cook, stirring occasionally, for about 20 minutes until the onions are deeply caramelized and golden brown.
Add the minced garlic, black pepper, and dried thyme to the onions. Cook for 1 minute until fragrant.
Add the dry spaghetti pasta to the pot, then pour in the vegetable broth and water. Stir to combine and make sure the pasta is submerged.
Bring the mixture to a boil over high heat, then reduce to medium-low and simmer uncovered for 12 to 15 minutes, stirring occasionally, until the pasta is cooked al dente and most of the liquid is absorbed.
Remove the pot from heat. Stir in the unsalted butter and grated Parmesan cheese until melted and well combined.
Taste and adjust seasoning with additional salt and pepper if needed.
Sprinkle the chopped fresh parsley over the pasta before serving.
