Compound Butter is the secret weapon that makes your turkey actually taste good and stay juicy without you having to baste it every 15 minutes. It’s fancy-sounding but it’s literally just butter mixed with stuff. That’s it. You win Thanksgiving. Compound Butter is also amazing on steaks, fish, pretty much any meat, it’s all about how you spice it
Why This Works for Cooking for One
Turkey breast tenderloins don’t have skin you can stuff butter under, so you just slather this on top and it melts into the meat as it cooks. You’re making a small batch (3 tablespoons) that’s exactly enough for one tenderloin, and you can customize the flavors however you want.

Fresh herbs:
- The waste trap: Bunches cost $3, you use 2 sprigs, the rest dies in the crisper
- Better way: Buy herbs in a living pot ($3.99, lasts weeks on the windowsill), OR use 1 tsp dried herbs instead (much cheaper, lasts years)
Butter:
- The waste trap: None—this uses 3 tablespoons, you have the rest for other recipes
- Better way: Keep butter in the fridge, it lasts months
Garlic:
- The waste trap: Whole head goes bad after you use one clove
- Better way: Buy pre-peeled cloves, OR roast the whole head and freeze the cloves, OR use 1/2 tsp garlic powder
The Leftover Chain
After making this, there are NO leftovers:
- This recipe makes exactly enough for 1 turkey tenderloin
- If you want extra for other uses, double the recipe
But if you DO make extra compound butter:
- Freeze in ice cube trays → Pop out cubes for Brown Butter Corn, Mashed Potatoes, steamed vegetables, steak, fish, toast
- Lasts 3 months frozen, 5 days in the fridge
If you’re also working through:
- Extra herbs from Stuffing → Use the same herbs here
- Leftover garlic from Brown Butter Corn → Mince it for this
- Lemon from another recipe → Add lemon zest for brightness
Coming from another recipe?
- This is made specifically for Turkey Tenderloin
- Use extra on Mashed Potatoes or Brown Butter Corn
Storage Reality Check
- This finished butter: 5-7 days in the fridge wrapped in plastic wrap or in a small container
- Frozen: 3 months in freezer (wrap tightly or use ice cube trays)
- On the turkey: Can apply it the night before and refrigerate until ready to roast
- Room temperature: Soften butter before mixing (easier to blend)
Pro tip: Make a double or triple batch and freeze it in a silicone ice cube tray. Pop out one cube whenever you need to make vegetables taste restaurant-fancy or want to make another turkey.

Single-Serving Pro Tip
Write the spice combo you used on a piece of tape and stick it to the plastic wrap. Next year when you’re trying to remember “what did I put in that butter that made it so good?” you’ll actually know. Trust me on this.

- 2 tsp seasoning = about 1 tsp dried herbs + 1/2 tsp garlic powder, or any combo
- Fresh herbs: use 1 tbsp fresh instead of 1 tsp dried
- Make extra: Double or triple the recipe and freeze in ice cube trays for future meals
