The sweet potato pb banana toast is a simple breakfast built from a slab of roasted sweet potato, a layer of peanut butter, and sliced banana on top. It trades bread for a vegetable base that stays firm under wet toppings and adds a gentle sweetness without refined sugar. This version gives you a reliable method so the slice crisps at the edge, holds its shape, and tastes balanced rather than soggy.
You get a plate that reads like toast but eats like a hybrid of snack and breakfast. The natural oils in peanut butter soften the dense flesh, while banana brings moisture and a lighter finish. It works as a quick weekday option or a laid-back weekend base you can dress up with spices or seeds. If you enjoyed this, our scottish potato scone is worth trying next. Making this sweet potato pb banana toast at home is surprisingly straightforward once you know the key steps.
Why You’ll Love These Sweet Potato Pb Banana Toast
- Uses one medium sweet potato to make four sturdy bases from a single vegetable.
- Naturally gluten free when you use pure peanut butter with no added malt or wheat fillers.
- Keeps you full longer than bread toast because the base is higher in fiber and resistant starch.
- Ready in about 20 minutes if you slice and roast while the oven heats.
- Flexible topping window: the base holds for a day, so you can prep it ahead and finish at work.
Ingredients You’ll Need
- 1 medium sweet potato (about 300g), scrubbed and cut crosswise into 4 slabs roughly 1.5cm thick
- 4 tbsp natural peanut butter, stir well if oil separates
- 1 large banana, ripe but firm, sliced into 8 rounds
- 1 tsp ground cinnamon
- 1 tbsp chia seeds
- 1 tbsp maple syrup
- 1 pinch sea salt
Ingredient Substitutions
Natural peanut butter: Replace with an equal amount of almond butter if peanut allergy is a concern. Almond butter is drier and less salty, so add a small pinch of salt and 1 tsp maple syrup to keep the same creamy-sweet balance. The flavor shifts nutty and mild rather than roasty, and the layer will look lighter in color. The sweet potato pb banana toast works well for weeknight cooking when time is limited.
Sweet potato: Swap for a firm purple yam of equal thickness if available. Purple yam holds shape well but cooks slightly denser, so extend roast time by 5 minutes. The base turns deep violet and reads more starchy, pairing better with tart banana than very sweet ones. Storing leftover sweet potato pb banana toast correctly keeps it tasting good for days.
Banana: Use 120g of sliced apple if banana isn’t on hand. Apple brings crunch and a sharper sweet-tart note, but releases less moisture so the peanut butter stays thicker. Expect a firmer bite and a shorter topping window before the apple browns. For the best results with this sweet potato pb banana toast, read through all the steps before starting.
Maple syrup: Replace with an equal amount of honey if not strictly vegan. Honey flows thinner and browns faster under heat, so skip broiling the top if you add it before roasting. The finished toast tastes rounder and a touch floral compared to maple’s woodsy note. For another easy option, check out our using canned beef.
Step-by-Step Instructions
- Heat the oven to 200°C / 400°F and line a sheet pan with parchment. Place the sweet potato slabs in one layer with space between them so steam escapes.
- Roast on the middle rack for 18–22 minutes until the underside is golden and crispy and a knife slides in with slight resistance. Flip and roast 6 more minutes.
- Spread 1 tbsp peanut butter on each warm slab, edge to edge, while the surface is still hot so it loosens into a glossy layer.
- Lay 2 banana slices on each, then scatter cinnamon, chia, and salt. Drizzle maple syrup and serve, or cool the base only for later use.
Pro Tips
Cut slabs to a matching thickness so they finish at the same time; uneven pieces leave one raw and one dry. A sharp chef knife makes the clean crosswise cut easier than a serrated one.
Roast the base without topping and store it; the peanut butter goes on after reheating so it doesn’t turn oily. This also lets you pack the plain slice in a lunch box with toppings separate.
Press chia into the peanut butter lightly so it adheres instead of rolling off when you lift the toast. The seeds soften in 10 minutes and add a gentle crunch before that.
Broil the topped toast for 2 minutes only if you want the banana edges caramelized; watch closely because sugar burns fast. Pull it the moment spots turn brown.
Common Mistakes to Avoid
Slicing too thin makes the slab collapse under peanut butter weight and turn mushy. Keep at least 1.2cm thickness so the flesh stays structured after roasting.
Skipping the flip means the top stays pale and waxy while the bottom browns. Turn once at the halfway mark for even texture and a cooked-through center.
Using cold peanut butter straight from the fridge leaves lumps that tear the soft flesh. Let it sit at room temperature for 15 minutes or warm the jar briefly in hot water. You might also like our lamb lollipop.
Serving Suggestions
Plate two slabs as a breakfast with a boiled egg on the side for extra protein. The french toast makes a good weekend alternative when you want a bread base instead.
Add a handful of spinach under the banana for a savory turn, or pair the plate with cherry almond smoothie for a light sweet side. The toast also works as a post-workout snack on its own.
Storage and Reheating
Roasted untopped slabs keep in an airtight container for up to 4 days refrigerated. Reheat in a toaster oven at 180°C / 350°F for 5 minutes until the edge firms again.
Freeze plain slabs for up to 2 months between parchment sheets; thaw overnight before reheating. Once peanut butter and banana are added, eat within 2 hours at room temperature to avoid spoilage.
Recipe Variations
Cocoa Version
Stir 1 tsp unsweetened cocoa into the peanut butter before spreading for a chocolate-nut base. The banana reads sweeter against the bitter note, and the color turns light brown. Skip maple syrup so the cocoa stays pronounced.
Savory Spin
Replace banana with 4 tbsp mashed avocado and omit maple syrup for a lunch-style toast. Add chili flakes for heat and keep cinnamon out. The flesh pairs better with the soft fat than the sweet fruit version.
Seed Butter Swap
Use sunflower seed butter instead of peanut for a school-safe plate, same 4 tbsp total. The layer is paler and a bit grainy, so warm it slightly to spread smooth. Banana and cinnamon stay as written.
Crunch Top
Add 2 tbsp toasted oats over the banana for a cereal-like finish. The oats crisp in the broiler step and give a dry counter to the soft fruit. Use banana bread crumbs if you have stale loaf on hand.

Ingredients
Instructions
-
Heat oven and prep pan
Heat the oven to 200°C / 400°F and line a sheet pan with parchment. Place the sweet potato slabs in one layer with space between them so steam escapes and they roast instead of steaming.
-
Roast sweet potato slabs
Roast the slabs on the middle rack for 18–22 minutes until the underside is golden and crispy and a knife slides in with slight resistance. This shows the flesh is tender but still structured, not mushy.
-
Flip and finish roasting
Flip each slab and roast for 6 more minutes at the same temperature. The top should lose its pale waxy look and cook through so the center is evenly done.
-
Spread peanut butter
Spread 1 tbsp peanut butter on each warm slab, edge to edge, while the surface is still hot so it loosens into a glossy layer. Use room-temperature peanut butter to avoid lumps that tear the soft flesh.
-
Add banana and toppings
Lay 2 banana slices on each slab, then scatter cinnamon, chia, and salt over the top. Press chia lightly into the peanut butter so the seeds adhere instead of rolling off when lifted.
-
Drizzle and serve
Drizzle maple syrup over the topped slabs and serve right away, or cool the base only for later use. If serving later, add peanut butter and banana after reheating so the topping stays fresh.
