Strip Steak with Onion Sauce

Strip Steak with Onion Sauce

Need an amazing Father’s Day dinner that won’t keep you in the kitchen all day? This Strip Steak with Onion sauce is just what you’re looking for.

Caramelized onions are one of my favorite toppings, so are these mushrooms…but then I found a recipe for onion sauce. Onion sauce? I had to check it out. This onion sauce is sort of like caramelized onions…but better.

The onions are cooked down in the same way, low and slow, but these onions get some white wine and cream to make it more of a sauce than just caramelized onions. And trust me when I say that it’s worth the half and hour it takes to make these.

You can do the onions ahead and then just grill up your steak at dinner time. More time to spend with Dad that way.
