Caramelized Onions and Fava Beans with Parmesan
Buttery caramelized onions meet tender fava beans in this simple vegetable side dish, finished with broiled melted parmesan for a nutty, golden crust. The sweet depth of slow-cooked onions balances the earthy beans, making this an elegant accompaniment to roasted meats or a light vegetarian main. Serve warm as a side or light lunch; the make-ahead option lets you prep components in advance and finish moments before the table.

Tips
Fresh fava beans need blanching and peeling to remove the bitter outer skin; this step is essential for the best texture and mild flavor.
Caramelize onions slowly over medium heat without rushing; the 20-minute timeframe allows natural sugars to develop deep sweetness.
Good to Know
Cooked beans and onions keep refrigerated up to 3 days in an airtight container. Do not store broiled cheese separately; broil only before serving.
Prepare through the step where beans are added to caramelized onions and transferred to the casserole dish. Cover and refrigerate up to 1 day. Sprinkle cheese, then bake at 350F for 25 minutes and broil for the last few minutes to brown the cheese.
Serve warm as a side dish to roasted chicken, lamb, or fish. Also works as a light vegetarian main with crusty bread.
Common Mistakes
Overcook fava beans to avoid mushy texture; aim for tender but intact.
Skip peeling the outer membrane on fresh fava beans to avoid bitter flavor.
Cook onions too fast on high heat to avoid burning; medium heat ensures even caramelization.

FAQ
Can I use all frozen or canned fava beans to save time?
Yes, frozen and canned beans work well and skip the blanching step. Ensure frozen beans are cooked before adding; canned beans are ready to use. Flavor and texture remain excellent.
What if I don't have an ovenproof skillet or dish?
Transfer the cooked beans and onions to any ovenproof baking dish or casserole before adding cheese and broiling. Cast iron, ceramic, or glass all work.
How long can I store the finished dish?
Once broiled, eat within 1 day refrigerated. The cheese best stays crispy if served immediately. Reheat gently in a low oven rather than the microwave to maintain texture.
