For a richer flavor, use heavy cream instead of milk. Add a pinch of red pepper flakes for a touch of heat. To save time, you can caramelize the onions in advance and store them in the refrigerator for up to 3 days. A splash of dry white wine during the caramelization process adds another layer of complexity.

Follow The Directions
01
Step
10 mins
Bring a large pot of salted water to a rolling boil. Add the pasta and cook according to package directions until al dente, about 8-10 minutes. Reserve about 1/2 cup of pasta water before draining. (10 min)
02
Step
5 mins
While the pasta is cooking, melt the butter and olive oil in a large, deep skillet over high heat. Add the sliced onions and cook, stirring occasionally, until they begin to soften and take on a slight color. (5 min)
03
Step
20 mins
Add the sugar, salt, pepper, balsamic vinegar, and water to the skillet with the onions. Continue cooking over high heat, stirring frequently, until the onions are very tender, deeply caramelized, and a rich dark brown color, about 15-20 minutes. Reduce heat if necessary to prevent burning. (20 min)
04
Step
2 mins
Reduce the heat to low. Add the milk (or cream), sliced garlic, and thyme leaves to the skillet. Stir to combine. (2 min)
05
Step
3 mins
Using an immersion blender, carefully blend the sauce directly in the skillet until it is smooth and creamy. Alternatively, transfer the sauce to a regular blender and blend until smooth, then return to the skillet. (3 min)
06
Step
2 mins
Drain the cooked pasta, reserving the pasta water. Add the pasta to the skillet with the caramelized onion sauce. Toss to coat, adding a little of the reserved pasta water if needed to reach your desired consistency. (2 min)
07
StepServe immediately, garnished generously with freshly grated Parmesan cheese.
