A coated component (100), along with methods of its formation, are provided. The coated component (100) includes a ceramic matrix composite substrate (102) comprising silicon carbide and having a surface (103), a bondcoat (104) on the surface (103) of the substrate (102), and an environmental barrier coating (108) on the bondcoat (104). The bondcoat (104) includes a plurality of discrete particles (110) dispersed within a matrix phase (112), with the matrix phase (112) formed from mullite and defining 60% to 98% by volume of the bondcoat (104). The plurality of discrete particles (110) includes an oxygen getter and has 50% of its volume or greater formed from particles having an average size of 10 µm to 100 µm.
