Bubble and squeak is a deeply caramelized, homey cake of leftover mashed potatoes and other vegetables, traditionally made the morning after a Sunday roast. This classic British dish gets its name from the cooking process: As the moisture from the vegetables bubbles away, the vegetables sizzle and squeak — especially the cabbage, a common addition. Be sure to let the bottom brown and crisp, mix those bits into the mash, then repeat until the cake is strewn with golden vegetables throughout. Eat alongside a fried or poached egg for breakfast. To make it vegetarian, replace the bacon with 2 tablespoons of olive oil.

Preparation

  1. Step 1

    In a large (12-inch) nonstick or well-seasoned cast-iron skillet, set the bacon over medium heat. Once sizzling, cook, stirring often, until darkened at the edges, 2 to 4 minutes. Add the onion, season with salt and pepper, and cook until softened, 2 to 4 minutes. Stir in the chopped vegetables and cook until browned in spots, 4 to 6 minutes.

  2. Step 2

    Add the butter. Once melted, add the potatoes and stir to combine. If using roasted potatoes, mash them with a potato masher or fork. Press into an even layer that fills the skillet. Cook until golden brown underneath, 4 to 6 minutes.

  3. Step 3

    Use a spatula to flip portions of the potato mixture, then press down to fill the skillet. Repeat, flipping when the bottom is golden brown, about every 4 minutes, and pressing down to fill the skillet until the mixture is browned and crisp throughout, another 8 to 10 minutes. If you don’t see sizzling around the edges, add another pat of butter; it will depend on your potatoes (see Tip).

  4. Step 4

    Press the mash into a compact cake (it might be soft or crumbly; that’s OK). Place a plate or cutting board over the skillet, then flip the cake onto the plate. If the cake falls apart, just press it back together. Sprinkle the top with salt and pepper. Serve scoops of the bubble and squeak with a poached or fried egg, if desired.

Tip
  • Be sure to add enough butter to get those potatoes browned. It will depend on whether you’re using a buttery potato like Yukon Gold or a starchy potato like russet. Also, your leftover mashed potatoes probably include milk or butter in them, so they may not need more butter, but if you’re using plain boiled or roasted potatoes, the skillet could look dry.

I think of this as a method, not a recipe. Whatever I have leftover in the fridge gets pan-fried and stirred to build up the crispy bits. Maybe I cook an egg as well. No need to get too precious, this is casual breakfast food. You do it because you have leftovers that need eating up and you'd rather have them hot and with crunchy bits than cold and soggy and sad. If you don't have leftover potatoes, cut one up and microwave for 4-6 minutes, then stir into the veggies.

My grandma from England made this with many variations. And it became go to words for leftovers. Loved it as a child and love it as a grandma myself. Thank you, Pansy Pearl!

If you end up not using the bacon fat, you're not going to get any bubbling or squeaking because you can't really get the flame hot enough to avoid burning the oil with non meat-based fat. If you really wanted to bubble and squeak, you have to use bacon drippings or lard.

Followed the recipe, which is basically how my Ma made it. My leftover veggies were certainly not we ate growing up! But delicious!

Made this last nite. Boiled 6 potatoes. Then, in a large wok, fried them in oil and butter with onions, cabbage, peas, and broccoli. The only thing that browned was the pan. Soaked it over9

My Brit mum-in-law taught me about this dish when visiting her in the UK. She always included leftover cabbage, but sometimes would add leftover kale or spinach or even turnip mash. There is a Scottish version called rumbletythumps, which I think did include turnip or rutabaga (swede, as it is called in the UK). British bacon was a deluxe addition, as was a bit of leftover Sunday roast. Every working class cook around the world has ways of using up odds and ends to make 'bonus' meals!
