A coated component, along with methods of its formation, are provided. The coated component may include a ceramic matrix composite substrate comprising silicon carbide and having a surface, a bond coat on the surface of the substrate, and an environmental barrier coating on the bond coat. The bond coat includes a plurality of discrete particles dispersed within a matrix phase, with the matrix phase formed from mullite and defining 60% to 98% by volume of the bond coat. The plurality of discrete particles include an oxygen getter and has 50% of its volume or greater formed from particles having an average size of 10 μm to 100 μm.
