Do you have that one go-to meal? It's relatively cheap, quick, you can make it without a recipe in front of you? This one is mine.
It's evolved a bit over the years. There have been many different variations. I used to make it as a slow-cooker meal with stew meat. Then it became a slow cooker meal when I had fresh venison. Venison stroganoff -- god, I wish I knew a hunter right now.
But now, this recipe has become a 30-minute meal. I use a better cut of beef since it isn't marinating or braising for any long period of time. On the nights I have more time, I barbecue the steak in the backyard. Grilled steak flavor in stroganoff is unequaled.
Steak. Butter. Onions. Mushrooms. Sour Cream. Nutmeg. Egg Noodles. Salt and Pepper. Doesn't that just scream "COMFORT FOOD"?
Add the sour cream. How much. That's up to you. I start with about 3/4 cup and then add more depending on how juicy the meat and veggies were. You certainly don't want a runny stronganoff. There have been times that I've had to add flour or arrowroot powder to help thicken it up.
