Rouladen is one of my families favorite recipes. My husband grew up eating rouladen. His mother makes the best rouladen. They are actually pretty simple to make.
Rouladen: Begin by buying Bottom round steak think sliced. Children will eat 1-2 rolls as where a man might eat three. You might even want to just make a couple for leftovers the next day. Salt and pepper your meat. Then spread Dijon mustard on each slice then lay a piece of bacon on top. Then add a slice of onion and a slice of pickle. From the smallest corner begin rolling until it looks like a fat cigar. secure closed with a tooth pick. In a skillet with a tablespoon of olive oil you will brown the rolls on all sides. Then take meat out and place on the side will you make the sauce. Add a teaspoon of garlic to the pan and saute but don't burn. Deglaze your pan with 2-3 cups of beef stock or red wine. If you choose to use wine the alcohol will cook out, so no worries of getting anyone drunk. Whisk in a tablespoon or two of cornstarch just will depends on how thick you want your sauce to be. Return meat to pan and simmer on low for about an hour to an hour and a half. The meat should be fork tender. This can be made in the crockpot for 6 hours, but you will want to make the sauce afterwards in a saucepan. Serve over spaetzle or mashed potatoes.
