Sweet potato toast with avocado swaps bread for roasted sweet potato slices that come out of the toaster crisp on the edges and soft in the middle, then gets topped with smashed avocado, a squeeze of lime, and a shake of chili flakes.
I started making this on mornings I was out of bread but had sweet potatoes sitting in the pantry. Turns out the swap works better than I expected.
The slices need to be even, about 1/4 inch (6mm) thick, or the middle stays hard while the edges char. Three full toaster cycles gets you there most days.
It’s naturally gluten free, holds up as a weekday breakfast, and comes together in 20 minutes start to finish.
Why You’ll Love This Recipe
- Uses the toaster, no oven wait required on busy mornings
- Naturally gluten free without any special flour swaps
- Ready in 20 minutes with just five main ingredients
- Sturdier base than bread, holds toppings without going soggy
Ingredient Notes
- sweet potato: Pick one that’s uniform in shape so all four slices come out the same thickness and cook evenly.
- avocado: Use one that yields to gentle pressure at the stem end. A rock-hard avocado won’t mash smooth.
- lime juice: Bottled works in a pinch, but fresh lime brightens the avocado more.
- everything bagel seasoning: Swap for toasted sesame seeds plus a pinch of garlic powder if you don’t have a jar on hand.
- red pepper flakes: Skip for kids or swap for a dash of smoked paprika for color without the heat.
Crispy Sweet Potato Toast with Avocado
Ingredients
Method
- Scrub the sweet potato and trim both ends. Slice it lengthwise into 4 planks, each about 1/4 inch (6mm) thick. Keep the slices as even as possible so they cook at the same rate.
- Brush both sides of each slice lightly with olive oil if using, then set them upright and ready to load into the toaster.
- Load the sweet potato slices into the toaster and run it on the highest setting for 3 full cycles, about 9 to 12 minutes total. Let the toaster cool for a minute between cycles if it feels hot to the touch.
- Check doneness by sliding a fork into the thickest part of a slice. It should meet just a little resistance, not go in hard. If the outside browns before the center softens, transfer the slices to a 200C/400F oven for 5 to 8 minutes to finish.
- Season the warm slices with the 1/4 tsp salt right out of the toaster.
- While the sweet potato toasts, halve and pit the avocado. Scoop the flesh into a mixing bowl and mash with a fork, leaving a few small chunks.
- Stir in the lime juice and a pinch of salt until just combined.
- Spread the mashed avocado evenly over each warm sweet potato slice.
- Sprinkle with red pepper flakes and everything bagel seasoning. Finish with a pinch of flaky sea salt and serve right away.
Notes
- Slice sweet potato lengthwise, not into rounds, for pieces long enough to fit the toaster slot.
- Even 1/4 inch (6mm) thickness matters more than exact size here.
- Don’t skip the salt directly on the sweet potato, it needs seasoning underneath the avocado.
- Have an oven backup ready if the toaster struggles to cook the center through.
Tips for Success
- Cut sweet potato slices exactly 1/4 inch (6mm) thick so they cook through without burning the edges.
- Toast on the highest setting and run it through 3 full cycles, checking doneness with a fork after each one.
- Mash avocado right before serving so it doesn’t turn brown and grainy while it sits.
- Salt the sweet potato slice itself, not just the avocado, or the toast tastes flat underneath.
- Keep a sheet pan and 200C/400F oven ready as backup if your toaster slots are narrow or the potato won’t soften.
Variations
- Top with a fried egg and a drizzle of hot sauce for a heartier breakfast that holds you until lunch.
- Swap avocado for whipped feta and a drizzle of honey for a sweet-savory version.
- Add smoked salmon, capers, and a squeeze of lemon instead of lime for a brunch-worthy plate.
Storage and Reheating
Plain toasted sweet potato slices (without avocado) keep in an airtight container in the fridge for 4-5 days.
Reheat them in the toaster on a medium setting for 1-2 cycles, or in a 200C/400F oven for about 5 minutes, until warmed through and the edges crisp back up.
Mash fresh avocado each time you serve. Don’t store the toast fully assembled, the avocado browns and turns watery against the warm sweet potato within an hour.
Serving Suggestions
Sweet potato toast with avocado works well with a soft-boiled or fried egg on top, since the seasoning already leaning savory pairs with a runny yolk.
For a weekday breakfast, serve two slices per person with a mug of coffee or a small bowl of fruit on the side.
Scale it up for brunch by adding a platter of smoked salmon and eggs, extra lime wedges, and a bowl of microgreens so people can build their own.
FAQ
Why is my sweet potato toast still hard in the middle after toasting?
The slices are probably cut too thick or haven’t gone through enough toaster cycles. Aim for even 1/4 inch (6mm) slices and run them through 3 full cycles, about 9 to 12 minutes total. If the center still resists a fork, finish them in a 200C/400F oven for 5 to 8 minutes.
Can I bake the sweet potato slices in the oven instead of using a toaster?
Yes, this works well if your toaster slots are narrow. Lay the slices on a sheet pan and bake at 200C/400F for 20 to 25 minutes, flipping once halfway, until a fork slides through easily and the edges are lightly browned.
How far ahead can I slice the sweet potato for meal prep?
Raw slices can sit submerged in water in the fridge for up to 24 hours to stop browning, just pat them dry before toasting. Fully toasted slices keep even better, store them plain in the fridge for 4 to 5 days and reheat before topping.
What goes well with sweet potato toast besides avocado?
A fried egg with avocado, whipped feta, or smoked salmon all work in place of or alongside the avocado. Hummus with a drizzle of olive oil is another good swap if you want something lower in fat but still creamy.
Is sweet potato toast gluten free?
Yes, sweet potato toast is naturally gluten free since there’s no bread or flour involved. If you’re strict about cross-contact, use a toaster that hasn’t recently toasted wheat bread, or wipe out the crumb tray first.
What’s the difference between sweet potato toast and regular avocado toast on bread?
Sweet potato toast swaps the bread slice for a roasted sweet potato plank, so it’s naturally gluten free and lower in refined carbs, with a softer, slightly sweet bite instead of a crusty chew. The avocado topping and seasoning stay basically the same.
