Swaps and substitutions

For a dairy-free version, swap the milk and Gruyère for unsweetened oat milk and a melty plant-based cheese. For gluten-free needs, use gluten-free buns and replace the flour with a gluten-free thickener.

What to serve with it

Serve with crisp dill pickles, a simple green salad, or roasted potatoes to balance the rich burger and creamy sauce. A cold lager or sparkling lemonade also works well with the savory onion and cheese flavors.
