Slow cooker Mexican casserole. Huge flavours and a crispy cheesy crust - and no pre-cooking required!

When I first took the lid off my slow cooker, I wasn’t sure if I was going to post about this recipe – it’s not the most attractive dish I’ve ever made, and it turns out it’s really tricky to photograph the inside of a slow cooker. But, then I had a taste and my jaw dropped (not literally, not with a mouthful of food anyway) – this Mexican casserole is one of my favourite things that I’ve ever made in my slow cooker. So please look past its somewhat scruffy appearance and the slightly dodgy photos, and just think about how it tastes!

The texture of this casserole is actually pretty hard to describe – it’s not quite eggy, not quite bready, not quite spongy… it’s just a fluffy mixture that’s surprisingly filling at the same time. Along with my favourite Mexican-style ingredients (black beans, corn, coriander, jalapeños), it makes an awesome low-effort dinner. As with all of my slow cooker recipes, there’s absolutely no pre-cooking required – literally just add everything to the pot, give it a good mix, and you’re done. Easy peasy.

The best thing about this casserole is the crust around the edge. You know that weird ‘magic cake’ thing, where you just make one mixture, and as it cooks it separates into three distinct layers? Well, this casserole does a similar thing – the middle stays soft and fluffy, and the edge crisps up to form the perfect cheesy crust. It’s not quite like a quiche (it’s a bit spongier than that because of the flour), but it’s in the same vague family. Second cousins, perhaps. In a way it’s like a healthier way to make a quiche – you still get a crust, but without having to use any pastry.

We served this casserole as a meal in itself, but you could use it as a side dish too – make it a real Mexican feast. Nom nom!

  1. Looks awesome to me. Most things that come out of my slow cooker look a mess but taste awesome, it’s a shame really, as I often want to share them, but don’t have your photographing finesse! I’ll have to give this a go now I’ve found somewhere to buy black beans :)

  2. Is your 1/4 tsp. hot chili powder the type that is just hot pepper (like cayenne) or is it the flavor mix type chili powder(like chile powder, garlic and spices)? This sounds good.

    1. It’s just called ‘hot chilli powder’ and is just a fine red powder, but going on the ingredients it looks like it also contains ground cumin, garlic powder and even some oregano – who knew!! You can’t taste any of those things at all!

  3. haha crockpot meals can be some of the hardest to photo!! This sounds fantastic – I love when the edges get crisp and the center is nice and soft! And I can never get enough mexican meal ideas!

  4. Yum! Do you have to crack the lid to allow the steam to escape to get that crispy crust?

  5. This sound so good! I love cooking in my slow cooker but am often stuck for inspiration other than all the bog standard boring stuff! The best bit is that, looking through the ingredients list, I already have most of it in the cupboard/fridge. Lazy, one-pot dinner looks like it’s on the cards for tomorrow – looks so delicious I think I’ll tell the rest of the family that I’ve been slaving all day though!
