Notes
You can easily make this dish vegetarian or vegan, but swapping the sausages for a meat-free alternative. If you are using meat sausages, use any kind you like to add a different flavour.
If you don't like woody herbs like thyme, then you could use something more leafy like parsley or even chives.
Serve this sausage casserole on creamy mashed potatoes, or with some homemade potato wedges.
Add some extra greens by stirring in some spinach a couple of minutes before serving.
You could cook the sausages under the grill first to keep this dish lighter.
Why not finish this dish in the oven, and you could sprinkle some cheese on top so it goes a bit crispy.
Add some extra smokey flavour by adding some chopped up chorizo to the mix.
