Cast Iron Venison Backstrap — The Best Way to Cook Deer's Prize Cut
🦌 The Story Behind This Recipe
I'll never forget the first time I cooked backstrap for my whole family. It was November, about a week after I tagged my best buck — a 9-point I'd been watching on trail cam all summer. My dad drove three hours to celebrate, and I was terrified I'd overcook it. My hands were literally shaking when I put it in the cast iron. When I sliced into it and it was perfect — pink, juicy, butter-basted with garlic — my dad just said 'best steak I've ever had.' From a guy who grew up eating prime rib every Christmas, that meant everything. Now this is my go-to recipe every single season, the first thing I cook from every deer I bring home.

👨🍳 Step-by-Step Instructions
- 1
Remove backstrap from refrigerator 30–45 minutes before cooking. Pat completely dry with paper towels — surface moisture is the enemy of a good sear. Dry meat = better crust.
- 2
Generously season all sides with coarse sea salt and cracked black pepper. Don't be shy — venison has bold flavor that needs a proper seasoning.
- 3
Preheat your oven to 375°F (190°C). Place your cast iron skillet over high heat for 3–4 minutes until smoking hot.
- 4
Add olive oil to the hot skillet. It should immediately begin to shimmer. Place the backstrap in the skillet — you should hear an aggressive sear. Don't touch it.
- 5
Sear for 2–3 minutes per side until a deep brown crust forms. With tongs, also sear the ends for 30 seconds each. Total searing time: 6–8 minutes.
- 6
Reduce heat to medium. Add butter, garlic, rosemary, and thyme to the pan. As butter foams, tilt the pan and use a spoon to continuously baste the backstrap with the herb butter — 2 full minutes of basting.
- 7
Transfer the entire skillet to the preheated oven. Cook 6–10 minutes for medium-rare, checking internal temperature every 2 minutes after the 6-minute mark.
- 8
Remove when internal temperature reads 125°F (52°C) — it will rise to 130°F (54°C) while resting.
- 9
Transfer to a cutting board. Tent loosely with foil. Rest for 8–10 minutes — this is non-negotiable. Cutting too early loses all the juices.
- 10
Slice against the grain into ½-inch medallions. Optional: brush lightly with Dijon mustard for a subtle tangy finish. Serve immediately.
🏹 Hunter's Tips
- →You only get two backstraps per deer — treat them like the gold they are. Don't rush this.
- →Age your backstrap in the refrigerator for 3–5 days before cooking. Uncovered on a rack. This dry-aging concentrates flavor dramatically.
- →Remove all silver skin before cooking — that's the tough white membrane on the outside. A sharp fillet knife makes quick work of it.
- →Never cook backstrap past medium. Without fat marbling, venison dries out fast above 145°F. Medium-rare is the sweet spot.
- →Cast iron holds heat better than any other pan — critical for a proper sear on lean venison.
🍽️ Serve With
- •Garlic mashed potatoes (soaks up the pan butter beautifully)
- •Roasted root vegetables (carrots, parsnips, sweet potato)
- •Creamed spinach or sautéed wild mushrooms
- •Crusty bread for the pan drippings
🥡 Leftovers
Slice cold backstrap thin and use in venison sandwiches with horseradish sauce, or chop and add to morning scrambled eggs with the leftover herb butter. Reheating is not recommended — room temperature is better than microwave for leftover backstrap.
