Heat a large stainless steel or cast iron skillet over medium high heat and add the cooking oil. Season the steaks with salt and pepper.
Once the pan is hot, sear the steaks on both sides and cook until you reach your desired internal temperature. I like mine cooked to around 125 degrees F internal temperature. Transfer the deer steaks to a plate to rest.
Make the Sauce
Lower the heat to medium. Add the red onion and cook for 2 to 3 minutes while stirring often. Add the mushrooms, season with salt and pepper. Cook the mushrooms until slightly tender, about 3 to 5 minutes. Add the garlic and cook for around 1 minute.
Remove the pan from the heat and add the bourbon (or brandy). Carefully light the brandy with a long match.
When the flame dies, add the stock, heavy cream, mustard and thyme leaves. Bring the mixture to a simmer. Cook until the sauce has reduced its volume by half. The sauce should coat a spoon when it's ready. Add the cooked artichoke hearts and warm through.
Add in the fresh chopped parsley. Season to taste with salt and ground black pepper.
Slice and Serve
Slice the steaks across the grain at around 1/4 inch thickness. Top with the sauce or serve on the side.
NOTES
Steak doneness matters: Venison backstrap is best served rare to medium-rare (120–130°F). Overcooking will dry it out quickly.
Let the steaks rest: Always rest your venison steaks for 5–10 minutes under foil to lock in moisture.
Venison sauce tip: If you don’t want to flambé with bourbon, just let the alcohol simmer off. A good brandy also works beautifully in this recipe.
Make-ahead: The mushroom cream sauce can be made 1–2 days in advance and reheated gently. It also freezes well for up to a month.
Pairings: Serve with pasta, mashed potatoes, or wild rice for a full venison steak dinner.
