You’ll also need:
20 cm square cake tin, fully lined with non-stick baking paper
Let’s Get Started
Preheat your oven to 200°C (400°F). Lightly brush the lined 20 cm square cake tin with olive oil.
In a large bowl, whisk together the plain flour, cornmeal, salt, baking powder, caster sugar, mustard powder, and cayenne pepper until evenly combined.
Stir in the grated cheddar, chopped red chilli, and sliced spring onions so they’re evenly distributed through the dry mixture.
In a separate bowl, whisk together the melted butter, buttermilk, and beaten eggs until smooth.
Pour the wet ingredients into the dry ingredients and gently fold until just combined. Do not overmix — the batter should be thick but scoopable.
Spoon the batter into the prepared tin and smooth the top. Bake for 25–30 minutes, or until golden and a skewer inserted into the center comes out clean.
While the cornbread bakes, prepare the crispy onions. Heat vegetable oil in a deep saucepan to 170–180°C. The oil should be hot but not smoking.
In one bowl, mix the flour, mustard powder, garlic salt, and cayenne. In a second bowl, beat the eggs. Place the cornmeal in a third bowl.
Dip the halved spring onions first into the seasoned flour, then into the beaten egg, and finally coat in cornmeal.
Carefully fry the coated onions in batches for 2–3 minutes until golden and crisp. Remove with a slotted spoon and drain on paper towels. While still warm, sprinkle with lime zest and a squeeze of lime juice.
For the chipotle mayonnaise, mix together the mayonnaise, soured cream, chipotle paste, and lime juice until smooth. Adjust spice and acidity to taste.
Once the cornbread is baked, allow it to cool for 10 minutes before lifting from the tin. Top generously with the crispy onions just before serving.
Servings and Pairing
This serves 8–10 as a side. Pair with chili con carne, grilled meats, BBQ chicken, or hearty soups. The chipotle mayo also doubles as a dip for roasted vegetables.
Variations
Swap cheddar for pepper jack for extra heat.
Add cooked sweetcorn kernels for extra texture.
Drizzle honey over the top for a sweet-spicy contrast.
Use jalapeños instead of red chilli for a smoky kick.
Storage Tips
Store cornbread in an airtight container for up to 3 days. Reheat slices in the oven to refresh texture. Crispy onions are best made fresh but can be reheated briefly in a hot oven to restore crunch.
FAQs
Can I skip deep-frying?
Yes. You can shallow-fry or even air fry the onions, though deep-frying gives the crispiest texture.
Can I make this ahead?
Bake the cornbread in advance and store covered. Fry the onions just before serving for maximum crunch.
How spicy is this recipe?
It has a gentle warmth. Adjust cayenne and chipotle paste to suit your heat preference.
Final Thoughts
Cornbread with Deep-Fried Crispy Onions takes classic comfort food and adds bold flavor and irresistible crunch. With cheesy crumb, citrusy crispy onions, and smoky chipotle mayo, it’s a side dish that easily steals the spotlight.
