Roasted Onion and Musroom Burgers with Potatoes--A one pan meal.

Roasted Onion and Mushroom Burgers with Potatoes

Roasted Onion and Mushroom Burgers with Potatoes is a one dish meal that gets a family friendly dinner on the table in no time.  It’s simple, delicious, and is the perfect meal for a busy weeknight.  I created this meal when my family requested burgers and roasted potatoes, but the burgers were still frozen, and my attention was needed in other places besides the kitchen.   What’s a mother to do?  I could’ve ordered takeout, but that would ruin our budget.    I carefully considered my options, and Roasted Onion and Mushroom Burgers with Potatoes came to my rescue.

I was inspired to attempt this recipe after my success with Roasted Leg Quarters and Potatoes.   I decided that I could create the same type of recipe using burgers, and I reasoned that I could start the burgers from their frozen state.  It’s important to note that these burgers were made from lean ground beef, and this recipe only worked because they were still  frozen.  If the burger patties had been thawed, they would have been burned to a crisp during the baking time, or the burgers would have been done and the potatoes would have been only partially cooked.

I sliced potatoes and seasoned them with seasoned salt and tossed them with 1 tablespoon of olive oil, topped the potatoes with sliced onions, and topped the onions with seasoned FROZEN hamburgers.    I remembered the mushrooms that I needed to use from the fridge, so I sliced them and put them on top of the burgers.    Then, I popped the pan in a 425 degree oven.  I started peeking in the oven after 40 minutes to make sure that the burgers weren’t burning.  An hour after I first put them into the oven, I removed the pan, but I was disappointed to discover that the mushrooms had become dried out  in the oven.   It was like having dehydrated mushrooms on our burgers.  Roasted Onion Mushroom Burgers with Potatoes Nevertheless, I  placed mushroom topped  burgers on buns, and put some of the oven roasted onions from the pan on top of each burger.  Finally, I added some potatoes as a side.  Burgers were dressed according to individual tastes.

Everyone loved the Roasted Onion and Mushroom Burgers with potatoes.   My worry about my dehydrated mushrooms was unnecessary.  Sue Chef loved their flavor, and wanted me to make the mushrooms again.   Bus Boy and Food Critic were too busy eating to say anything.  The best part about this meal was that I was able to attend to other things while dinner roasted away in my oven.

Roasting frozen burgers with potatoes, onions, and mushrooms creates a simple and delicious one dish meal. The burgers, onions, and mushrooms can be served on a bun topped with your favorite toppings along with a side of the potatoes. It's a perfect meal for a busy night. Cook's Note: Use only frozen burgers made from lean ground beef. Regular ground beef will add too much grease to the pan, and if the burger's are not frozen, they will burn before the end of the cooking time.
