Thaw out Angus beef patties. This can be done in the microwave. (That's faster than just letting the meat sit and thaw.)

Chop up onion into as big of pieces as you want

Cut patties in half.

Situate patties in pan.

Scatter chopped onion across patties.

Pour in water until at height in pan that you need and want.

Scatter flour over patties and onion.

Make sure flour and water is mixed well in pan.

Place pan in oven at 350° for 40 minutes.

Take pan out of oven and enjoy meal. I like it with mashed potatoes and green beans.
