Method
- Peel and cube potatoes into 1-inch pieces. Place in large pot, cover with cold water by 1 inch, and add salt. Bring to boil over high heat, then reduce to simmer. Cook 12-15 minutes until completely tender when pierced with fork.
- While potatoes cook, season chicken breasts generously with salt and black pepper on both sides. Heat 1 tablespoon olive oil in large skillet over medium-high heat. Add chicken and cook undisturbed 6-7 minutes on first side until golden brown. Flip and cook 6-7 minutes more until internal temperature reaches 165°F. Remove to plate and tent with foil.
- Reduce skillet heat to medium. Add 2 tablespoons butter and let melt. Add minced garlic and stir constantly for 1 minute until fragrant but not browned.
- Sprinkle flour over garlic and butter, stirring to create a paste. Cook 1-2 minutes, stirring constantly, until lightly golden and nutty-smelling.
- Slowly pour in chicken broth while whisking constantly to prevent lumps. Scrape up browned bits from bottom of pan. Simmer 3-4 minutes until gravy thickens enough to coat back of spoon. Stir in heavy cream if using. Season with salt and pepper to taste.
- Drain potatoes well and return to pot. Add 2 tablespoons butter and ½ cup milk. Mash until smooth, then fold in shredded cheddar cheese until melted and creamy. Season with salt and pepper.
- Spoon cheesy mashed potatoes onto plates. Top with chicken (sliced or whole) and ladle hot garlic gravy over everything. Garnish with fresh chopped parsley or chives.
Notes
Storage: Store chicken with gravy and mashed potatoes separately in airtight containers in refrigerator for up to 3 days. Reheat potatoes with splash of milk. Reheat chicken and gravy together in skillet over medium-low heat with splash of broth if needed.
Tips: Pound chicken to even thickness for uniform cooking. Warm milk and butter before adding to potatoes for smoother texture. Don't overwork potatoes when mashing to avoid gluey texture.
Variations: Add 8 oz sliced mushrooms to gravy for mushroom garlic version. Use chicken thighs for juicier, more flavorful meat (add 2-3 minutes cook time). Try Gruyère or smoked gouda instead of cheddar in potatoes.
Lighter Option: Replace half the butter and milk in potatoes with Greek yogurt. Skip heavy cream in gravy.
