Preheat the oven to 400°F (200°C). Prepare an oven-safe glass baking dish or a parchment-lined baking sheet.
Sauté the chopped onion in a skillet with a little cooking oil until softened and golden. Let cool slightly.
Combine the ground beef, eggs, breadcrumbs, cream, salt, garlic powder, paprika, and cooled onion in a large bowl. Add any optional seasonings. Mix gently until evenly combined.
Shape into 6–8 evenly sized patties and arrange in a single layer in the prepared dish.
Bake for approximately 25–35 minutes, depending on thickness, until the center reaches 160°F (71°C).
Serve warm with your favorite sides and spoon over some of the cooking juices.
