Sunday brunch has never looked or tasted so good! This easy, cheesy, spicy sausage croissant bake is big enough to serve the whole family and small enough to guarantee no leftovers — not that anyone would let this savory breakfast delight go to waste!

What we really love is that you can put everything together the night before and let it chill until morning. All we do the next day is pop it in the oven for a hassle-free brunch dish that is both filling and delicious.
