Veggie Sausage Casserole

Casseroles are up there in the leagues of ultimate comfort food. They are warming, easy to make and can feed a crowd, which makes them the perfect batch-cooking meal you can stow away in your freezer or whip out when you have lots of hungry mouths to feed. Casseroles are a simple dish which can easily be changed up.

This recipe is actually one I have adapted from a BBC Good Food recipe, the original which you can find here. I made mine vegetarian as I had a load of veggie sausages in the freezer which I wanted to use up. Below are some top tips for making this dish and some easy ways to mix it up. I don't usually write lengthy pieces before a recipe (because it's not my style of blogging - I like to get straight to the point!) but I felt this was needed. Feel free to scroll straight to the recipe otherwise!

Top Tips:

  1. Gravy or stock: I won't lie, I used Bisto Best Gravy granules. You can use fresh gravy you have made or buy it from a shop. You can also use veg or chicken stock to make this, but you will need to add a little cornflour to thicken the casserole. I usually have homemade gravy in the freezer but for moments like this, I use Bisto.

  2. Mash: Use the leftover oil from cooking the sausage to mix into your mashed potato. The flavor will be incredible. I used my homemade garlic butter in the mash also, for extra flavour.

  3. Oil: any basic vegetable or rapeseed oil will do but for added flavour you can use a herb or garlic oil. I used my own garlic oil as there was no garlic mentioned in the original recipe

  4. Taste: make sure you taste your casserole and add anything you think it needs. Also taste the mash and add more butter/oil/seasoning if you think it needs it

Make it vegan:

  • Ensure the veggie sausages are vegan friendly

  • If using stock, use vegetable & if using gravy, make sure its a Vegan one

  • Use only oil to bind your mashed potato and leave out the parmesan topping!

Make it meaty:

  • Use any type of meaty sausage you like. I would recommend Lincolnshire, venison/red wine or pork & apple sausages

  • Use a fresh meat gravy, chicken is advised by the BBC Good Food recipe, but I made mine with Bisto Best Beef Gravy!

  5. Whilst the potatoes are boiling you can make your casserole: roughly slice the chard and thinly slice the leeks into rounds
