Preheat your oven to 425°F and line a large roasting pan with foil for easy cleanup. Pat the turkey breast dry with paper towels, then season all sides generously with salt, pepper, and paprika.
In a small bowl, combine the softened butter, minced garlic, rosemary, thyme, and Dijon mustard into a fragrant paste. Rub this herb butter mixture all over the turkey breast, working it under the skin where possible for maximum flavor infusion.
Arrange the onion, carrots, and baby potatoes around the thanksgiving turkey breast crowd centerpiece in your roasting pan. Drizzle vegetables with olive oil and season with salt and pepper, then pour the chicken broth and lemon juice into the bottom of the pan.
Roast for 50 minutes, basting the turkey with pan juices every 15 minutes to keep the meat incredibly moist. The pan juices combine with melting garlic butter to create an irresistible glaze that browns the skin beautifully.
Check the internal temperature at the thickest part of the breast—it should reach 165°F. If skin isn't golden enough, increase oven temperature to 450°F for the final 5-10 minutes, watching carefully to prevent burning.
Remove from the oven and let it rest for 10 minutes before slicing. The resting period allows juices to redistribute throughout the meat, ensuring every slice stays tender and succulent rather than dry.
Transfer your garlic butter turkey to a serving platter, arrange roasted vegetables around it, and drizzle with pan juices. Serve immediately while everything is hot and the aromas fill your dining room.
