Ingredients
For the Sweet Potato Rounds
| Ingredient | Quantity | Notes |
|---|---|---|
| Sweet potatoes | 2 medium | Look for long, uniform ones for even rounds |
| Extra virgin olive oil | For drizzling | Use a good quality oil for best flavor |
| Sea salt | To taste | Plus extra coarse salt for finishing |
| Freshly ground black pepper | To taste | |
| Watermelon radish | 1 medium | Thinly sliced, cut into half moons |
| Sesame seeds (white or black) | 2 teaspoons |
For the Avocado Tartare
| Ingredient | Quantity | Notes |
|---|---|---|
| Sesame oil | 1 teaspoon | Toasted sesame oil adds the best depth |
| Fresh lemon juice | 2 teaspoons + more for squeezing | Freshly squeezed only |
| Dijon mustard | 1/4 teaspoon | Adds subtle tang to the dressing |
| Red onion, diced | 1/4 cup | Fine dice for best texture |
| Ripe avocado | 1 medium-large | Should yield slightly to pressure when ripe |
| Sea salt | To taste |
Step-by-Step Instructions
- Preheat your oven to 425 degrees F and line a large baking sheet with parchment paper.
- Slice the sweet potatoes into thin rounds using a sharp chef’s knife on a stable cutting board. Aim for slightly thicker than 1/8 inch but thinner than 1/4 inch. This should yield 14 to 16 rounds from the thick middle section of each potato. Set aside any end pieces to roast separately for another use.
- Season and roast: Arrange the rounds in a single layer on your prepared baking sheet. Drizzle with olive oil and season with pinches of sea salt and black pepper. Roast for 20 minutes.
- Flip and continue roasting for another 10 to 15 minutes, or until the rounds are tender and lightly caramelized at the edges.
- Make the avocado tartare: In a mixing bowl, whisk together the sesame oil, lemon juice, and Dijon mustard using a kitchen utensil. Add a few pinches of salt. Stir in the diced red onion and set aside to marinate while the sweet potatoes finish roasting. Use your measuring cups and spoons set for accuracy.
- Add the avocado: When the sweet potato rounds are almost finished, dice the ripe avocado and fold it gently into the tartare mixture. Add an extra squeeze of lemon juice to brighten the flavors and help prevent browning. Season to taste.
- Assemble the bites: Remove the roasted sweet potato rounds from the oven and let them cool for 2 to 3 minutes. Top each round with a slice or two of watermelon radish, followed by a generous spoonful of avocado tartare. Finish with a sprinkle of sesame seeds and a pinch of coarse sea salt.
- Serve immediately for the best texture and flavor.
Tips for the Best Sweet Potato Appetizer Bites
- Uniform slicing is key: Use a mandoline or a steady hand with your chef’s knife to get even rounds that cook at the same rate.
- Do not skip the flip: Turning the rounds halfway through roasting ensures both sides get a slight caramel edge and a tender center.
- Prep the tartare last: Avocado browns quickly. Dice it right before serving and always use fresh lemon juice to slow oxidation.
- Choose a ripe avocado: Press gently on the skin it should give slightly without feeling mushy.
- Make it ahead: You can roast the sweet potato rounds up to two hours in advance. Reheat briefly in the oven and assemble just before serving.
- Customize the toppings: Swap watermelon radish for regular radish, or add a drizzle of tahini for an extra layer of flavor.
Serving Suggestions
These Sweet Potato Appetizer Bites shine as a starter for a Mother’s Day brunch, a spring brunch gathering, or a casual holiday cocktail party. Arrange them on a large serving platter lined with fresh greens for a stunning presentation. They pair beautifully with a light sparkling wine or a citrusy mocktail.
If you are building out a full brunch menu, consider pairing these bites alongside floral desserts, a fruit salad, or a classic eggs Benedict for a well-rounded spread that will impress every guest.
Storage and Make-Ahead Notes
- Roasted sweet potato rounds: Store in an airtight container in the refrigerator for up to 3 days. Reheat in a 400 degree F oven for 5 minutes before assembling.
- Avocado tartare: Best made fresh. If you must store it, press plastic wrap directly against the surface and refrigerate for up to 4 hours.
- Assembled bites: Do not store assembled the avocado will brown and the rounds will soften. Always assemble just before serving.
Frequently Asked Questions
Can I make Sweet Potato Appetizer Bites ahead of time?
Yes. You can roast the sweet potato rounds up to two hours in advance and store them at room temperature. Prepare the avocado tartare no more than 30 minutes before serving and assemble right before your guests arrive for the freshest result.
What can I substitute for watermelon radish?
Regular red radish works perfectly as a substitute. You can also use thinly sliced cucumber for a milder, refreshing crunch that complements the avocado tartare beautifully.
Are Sweet Potato Appetizer Bites vegan?
Yes, this recipe is entirely plant-based. Every ingredient in both the roasted rounds and the avocado tartare is naturally vegan and gluten-free, making it an inclusive option for nearly any guest at your table.
How thin should I slice the sweet potatoes?
Aim for rounds that are slightly thicker than 1/8 inch but no thicker than 1/4 inch. Too thin and they will crisp up like chips; too thick and they will not roast through properly in the allotted time.
Can I use an air fryer instead of the oven?
Absolutely. An air fryer is a great alternative. Cook the sweet potato rounds at 400 degrees F for 10 to 12 minutes, flipping halfway through, until tender and lightly golden.
What other toppings work well on these bites?
Beyond the avocado tartare and watermelon radish, you can try goat cheese and honey, smoked salmon and cream cheese, or hummus and roasted chickpeas for equally delicious variations.
