• servings: 2 servings
• active time: 15 minutes
• total time: 50 minutes

Ingredients

1 Tbsp butter, divided

1 large onion, thinly sliced

1 tsp balsamic vinegar

1/8 tsp salt

1 tsp all purpose flour

2/3 to 3/4 cup vegetable broth, divided

2/3 cup whole milk

4 oz penne pasta

1/4 tsp dried thyme

1/2 cup freshly grated Parmesan cheese

2 cups spinach

Directions

Melt 1/2 Tbsp butter in a skillet over medium heat. Add onion; cook, stirring often, 1 to 2 minutes.

Cover skillet, reduce heat to medium-low, and cook 10 to 15 minutes, stirring occasionally, until onion is lightly browned and tender. Stir in vinegar and salt. Remove onion from skillet; cover and keep warm.

Melt 1/2 Tbsp butter in same skillet (don’t wipe it out). Stir in flour; cook 1 minute. Add 2 Tbsp broth, scraping pan to loosen browned bits.

Add remaining broth and milk, whisking until smooth. Add pasta and thyme; bring to a boil, reduce heat, and simmer until pasta is al dente. If pasta is dry or sauce too thick, add additional broth, if needed, 2 Tbsp at a time to thin it to desired consistency.

Stir in onion, cheese, and spinach until cheese melts and spinach wilts.
