Juicy, pan-seared hamburger steaks smothered in a rich and creamy dill sauce. A comforting one-pan dinner ready in 35 minutes – perfect served over mashed potatoes or egg noodles.
In a large bowl, combine ground beef, panko breadcrumbs, milk, egg, grated onion, minced garlic, salt, and pepper. Mix until just combined – do not overwork the meat.
Shape into 4 equal oval patties, about 1/2 inch thick.
Heat vegetable oil in a large skillet over medium-high heat until shimmering. Sear the hamburger steaks 3 to 4 minutes per side until deep golden-brown. Do not press down on the patties. Remove and set aside.
Reduce heat to medium. Melt butter in the same skillet. Add chopped onion and cook 3 to 4 minutes until softened. Add garlic and cook 1 minute until fragrant.
Sprinkle flour over the onion and garlic. Whisk constantly for 1 minute to cook out the raw flour taste.
Slowly pour in beef broth in a steady stream while whisking continuously. Bring to a simmer and cook until slightly thickened, about 2 to 3 minutes.
Stir in heavy cream, fresh dill, and Dijon mustard. Season with salt and pepper to taste.
Return hamburger steaks to the skillet. Reduce heat to low, cover, and simmer 8 to 10 minutes until internal temperature reaches 160 degrees F.
Garnish with extra fresh dill and serve hot over mashed potatoes, egg noodles, or rice.
Notes
Use 85/15 or 80/20 ground beef for the juiciest results. Leaner blends produce dry patties.
Do not press down on patties while searing – this releases the juices and dries out the meat.
Substitute sour cream or Greek yogurt for heavy cream for a tangier sauce – stir in off the heat to prevent curdling.
Fresh dill is strongly recommended but 1 tsp dried dill can be substituted.
The sauce thickens as it cools. Add a splash of beef broth when reheating to loosen it.
Store leftovers in an airtight container in the refrigerator up to 3 days or freeze steaks and sauce separately up to 3 months.
