What is a french onion pasta bake?
Like the name implies, this lasagna-esque dish takes inspiration from the classic recipe for French onion soup. Since French onion soup is typically topped with a layer of gooey cheese, the main flavors translate easily into a pasta-based dinner. Instead of making an onion-based soup we are taking the caramelized alliums and combining them with meaty mushrooms, almond-based Alfredo sauce, and warming Italian herbs.
How can I cook lasagna on the stovetop?
Lasagna noodles labeled as “no-boil” will cook very easily in a pan on the stovetop, right in their prepared sauce. To cook lasagna on the stovetop, simply poke broken pieces of the noodles underneath your already-simmering cheesy sauce and vegetable mixture. With the heat set to medium and the sauce simmering heavily, the noodles will cook right in the pan in just 10 minutes, with no oven required.
How to Prepare Caramelized Onions
- Add olive oil to a cast iron skillet over medium low heat. Add sea salt and sauté for 5 minutes, until golden. Stir to prevent sticking.
- Cover your skillet, turn heat to low, and let onions steam for 25-30 minutes. Check occasionally to ensure they’re not burning, adding a splash of water if needed.
- Remove the lid and deglaze the pan with white wine. Stir to let wine reduce. Repeat this process with the balsamic vinegar. Stir and add minced garlic, dried thyme, and optional red pepper.
- By this point your onions have been cooking for nearly 45 minutes, should be a dark brown and smell sweet. Turn off heat but leave onions in pan.
Can caramelized onions be made ahead? How long will they keep?
Yes, caramelized onions can be made ahead and will last in the fridge for 5 days. Given that this recipe can take some time for an average “weeknight” meal, I recommend making this portion ahead of time if you are able! With pre-made onions, this french onion pasta bake can be ready in just 20 minutes.
