Tips & Notes
Searing adds flavor but can be skipped if you’re short on time.
Add mushrooms or carrots for extra texture and nutrition.
Use turkey breast if you can’t find tenderloin — just adjust cooking time.
Fresh herbs (like thyme or sage) elevate the flavor even more.
Save leftovers for turkey sandwiches, wraps, or grain bowls.
Frequently Asked Questions
Q: Can I use frozen turkey tenderloin?
A: Yes, but thaw it completely in the fridge before cooking for food safety and even cooking.
Q: What’s the difference between turkey tenderloin and turkey breast?
A: Tenderloin is a lean, boneless part of the turkey breast — more tender and cooks faster.
Q: Can I make the gravy gluten-free?
A: Absolutely! Use gluten-free tamari and cornstarch instead of flour.
Q: Can I cook veggies in the slow cooker with the turkey?
A: Yes — try baby potatoes, carrots, or mushrooms under the turkey to soak up flavor.
Q: How do I store and reheat leftovers?
A: Store in the fridge for up to 4 days. Reheat gently in a skillet with extra gravy or microwave in 30-second bursts.
