This family favourite recipe has all your favourite veggie burger flavours but in a casserole form!

Our meat-free hamburger casserole is great for easy mid-week dinners, but it also makes a deliciously different main course for Easter, Christmas, or Thanksgiving. Serve it alongside your preferred vegetables and vegan gravy for tasty vegan comfort food.

Vegan Hamburger Casserole

The origins of the American hamburger or cheeseburger casserole are relatively recent, although Americans enjoy turning many dishes into casserole versions, making the hamburger casserole a very typical American invention!

Hamburger casserole is not well-known in the UK, but we couldn't resist creating a meat-free version as we knew our kids would love it. We're sure many families will add this meal to their monthly menu because it's a handy recipe that can be easily customized with ingredients you have on hand or need to use up.

For our vegan hamburger casserole recipe, we opted to use TVP (textured vegetable protein), a dried mince that needs rehydration. TVP is an inexpensive source of protein, high in fiber, cholesterol-free, low in calories and fat, and excellent at absorbing any flavours you add to it.

However, you can use any meat-free mince. We've made this casserole with both fresh and frozen vegan mince, and both work just fine.

Ingredients

The ingredients you will need for the casserole filling include textured vegetable protein (TVP), marmite or yeast extract, potatoes, carrots, celery, onions, garlic, soy sauce, vegan Worcestershire sauce, and dried mixed herbs.

For the cheesy sauce topping, you will need margarine, plain flour (all-purpose flour), plant-based milk (such as soy or oat), vegetable stock, and nutritional yeast flakes.

For the final topping, you will need breadcrumbs, vegan cheese, fresh tomatoes, gherkins or pickles if desired, and any other burger toppings you like - such as canned jalapeños or fresh sliced chilli's.

If you prefer, you can skip the breadcrumb topping and simply use vegan grated cheese or extra nutritional yeast flakes. For a quicker option, use a store-bought vegan white or cheese sauce.

Enjoy this casserole with your favourite veggie burger accompaniments, such as crisp lettuce and red onion rings. Be sure to include everyone's favourite condiments, like hot sauce, mustard, tomato ketchup, brown sauce, or vegan mayonnaise. Additionally, an onion gravy is a great accompaniment.

How to prepare

There are a few easy steps to preparing this vegan hamburger casserole: rehydrating the dried vegan mince, preparing the casserole filling, making the cheese sauce, and then assembling the casserole with the final toppings. To save time, you can prepare the casserole in advance and store it in the refrigerator for a day or so before cooking.

Step 10: Cook for 3-5 minutes, before removing from the heat and mixing through the nutritional yeast flakes. Season with salt and pepper.

Serving suggestion: Serve with crispy lettuce and red onion rings, accompanied by vegan onion gravy. Alternatively, top with your favourite veggie hamburger garnishes and serve with burger sides such as baked beans in tomato sauce, Boston baked beans, vegan coleslaw, pickled beetroot, etc.

Recipe Notes

Storing

Leftovers can be stored in the fridge, covered, for up to 3 days. The casserole can be frozen but the texture of the breadcrumb topping may be affected. For meal prep the casserole can be prepared up to the breadcrumb-cheese topping stage, and frozen minus the topping. Defrost, bring to room temperature, and add the topping just before baking.

Reheating

Bring the chilled casserole to room temperate and bake on the middle oven shelf at the cooking temperature, until piping hot throughout. You can add a cover over the casserole to avoid over browning if necessary, and sprinkle a few tablespoons of water over the casserole to help with reheating.

Is this hamburger casserole suitable for gluten-free?

To prepare our recipe as gluten-free, you will need to use gluten-free vegetable stock and gluten-free soy sauce. You will also need gluten-free vegan Worcestershire sauce, which is commonly found in the UK, or you can substitute it with extra soy sauce. Additionally, you will need to use gluten-free breadcrumbs.

We use Marmite or yeast extract to soak the TVP, but this ingredient is not gluten-free. If you cannot find a gluten-free version, you can omit this ingredient or replace it with gluten-free miso paste.

For the cheese sauce, use a gluten-free plain flour blend such as the Doves Farm Freee brand.

What can I serve with vegan hamburger casserole?

Anything you would normally have with your veggie burgers or meat-free hot-dogs can be enjoyed with a vegan hamburger casserole. Here are a few ideas:

* crispy lettuce

* sliced red onion rings/ green or spring onions, pickled onions

* cucumber

* any salad bits

* peas and sweetcorn

* corn-on-the-cobs

* green beans/ mangetout/ field beans/ asparagus

* sweet potato fries or wedges, ordinary potato fries or wedges

* any roast vegetables

* any steamed vegetables, especially green vegetables

* canned baked beans/ spaghetti hoops

* vegan gravy

* tomato ketchup/ brown sauce/ BBQ sauce

* vegan sour cream/ mayonnaise

* guacamole

* salsa

* mustard

* hot sauce/siracha

* vegan coleslaw

Can I substitute any of the ingredients?

A few suggestions:

* instead of potatoes use pasta or thick noodles

* not a fan of gherkins? replace with canned jalapeños or any pickle you like

* replace the white potatoes for sweet potatoes or butternut squash

* use cracker crumbs instead of breadcrumbs

* replace the vegan mince for crumbled vegan burgers or fine diced mushrooms

* sub out the celery for green bell pepper or courgette/zucchini

* for the topping omit the vegan grated cheese and use nutritional yeast flakes instead, about 4-6 tablespoons

Are there are shortcuts to preparing this vegan hamburger casserole?

Yes, there are a few shortcut ideas:

* use an already prepared vegan white sauce, such as a jar of vegan lasagna sauce and mix through the nutritional yeast flakes before covering the mince and potatoes. Or use a vegan cheese sauce packet and make up the sauce according to packet instructions.

* prepare the mince and potato mix in advance and store in the fridge for a day or two before proceeding with the recipe. The mix can also be frozen for 4-6 months.

* if you are in a rush the breadcrumb topping can be omitted or simply use extra vegan shredded cheese for the top

Is vegan hamburger casserole good for batch prep?

Yes this casserole is perfect for batch prepping. Prepare the casserole and freeze for 4-6 months, well wrapped in the casserole dish. But don't add the breadcrumb topping until you are going to bake. It is easy and saves time to batch prep an extra casserole along with the one your preparing for dinner. You'll definitely thank yourself later!

Any interesting ideas to repurpose leftover hamburger casserole?


* reheat and serve on a slice of toasted bread for next day's lunch

* mash the potatoes a little and use as a sloppy-joe filling for a crusty roll

* use as toasted cheese/grilled sandwich filling

* mix the leftovers with a can of baked beans and reheat, serve with vegetable sides

For a change, swap out the potatoes for pasta or thick ribbon noodles. Alternatively, you can skip the breadcrumb topping and simply sprinkle vegan grated cheese on top or nutritional yeast flakes, and bake until bubbly and golden.

  • Serve with your favourite veggie burger sides and sauces. Such as hot sauce, tomato ketchup, brown sauce, BBQ sauce, vegan sour cream or mayonnaise, guacamole, salsa, mustard, etc.

Notes

  • Nutritional information is provided for guidance only and is not a strict calculation as ingredients vary. 
  • Instead of TVP mince you can use 350-400grams of fresh or frozen meat-free mince.
  • Instead of vegan mince use 300 grams of mushrooms chopped really small into mince size pieces. A small food processor is great for crumbling the mushrooms into tiny pieces.
  • For a change replace the potatoes with pasta or thick noodles - adjust liquid quantities to suit.
  • The breadcrumb topping is optional, if you are in a hurry simply omit and just add grated vegan cheese or nutritional yeast flakes.
  • The cooked potatoes and mince can be enjoyed without baking as a casserole, just add extra water or vegetable stock to create a gravy and serve in a bowl. A slice of thick crusty bread to mop up the savoury gravy is nice.
  • Leftovers can be stored, covered, for 3 days.
  • Or frozen for 2-3 months.
  • Thaw before reheating. 
  • Reheat at the cooking temperature, you can add a layer of kitchen foil over the casserole to prevent over-colouring the top. Reheat for 25 -35 minutes until piping hot.
  • Leftovers are tasty served over a slice of toasted/grilled bread.
  • Or use the leftover casserole as a filling for grilled cheese toasties.
  • Alternatively, give the leftovers a mash and use as a sloppy joe filling.
