Crispy Cauliflower Po Boy Sandwich in Steps

Step 1: Prepare the Cauliflower
Begin by preheating your oven to 425°F (220°C). While the oven heats, wash and cut your cauliflower into small florets, ensuring each piece is about 1 inch in size.
Step 2: Make the Coating
In a mixing bowl, combine the Creole seasoning, lemon zest, and egg. Whisk together until well blended.
Step 3: Coat the Cauliflower
Add the cauliflower florets into the egg mixture and toss to coat completely. Once coated, sprinkle the cuppanko breadcrumbs over the top and mix until the cauliflower is well-covered.
Step 4: Bake the Cauliflower
Line a baking sheet with parchment paper and spread the coated cauliflower evenly on the sheet. Drizzle with extra-virgin olive oil. Bake in the preheated oven for about 25 minutes or until golden brown and crispy, flipping halfway through.
Step 5: Prepare the Sauce
While the cauliflower is baking, you can whip up the sauce. In a separate bowl, mix together the mayo, mustard, minced garlic, paprika, and hot sauce until smooth and creamy. Adjust the seasoning to taste.
Step 6: Toast the Baguette
Slice the baguette pieces and lightly toast them in the oven until just golden. This adds a delightful crunch to your sandwich.
Step 7: Assemble the Sandwich
Once the cauliflower is done baking, it’s time to assemble! Spread a generous layer of the creamy sauce on both sides of the toasted baguette. Layer with lettuce, sliced tomatoes, pickles, and top with the crispy cauliflower. Sprinkle with chives and add a lemon wedge on the side for an extra zing.
Step 8: Serve and Enjoy!
Serve your crispy cauliflower po boy sandwiches warm, and enjoy the incredible flavors and textures with every bite!
Holiday-Friendly Variations

- Sweet Potato Variation: Substitute half of the cauliflower with roasted sweet potato for a different flavor profile.
- Spicy Cajun Sauce: Swap the mayo sauce for a spicy remoulade using Cajun spices.
- Grilled Veggies: Add grilled bell peppers and onions for an extra layer of deliciousness.
- Vegan Option: Use a flax egg instead of a real egg and vegan mayo for the sauce.
Errors to Dodge
- Don’t overcrowd the baking sheet, as this can result in soggy cauliflower instead of crispy pieces.
- Ensure the oven is preheated to get that perfect crunch.
- Be careful not to burn the garlic in the sauce; add it at the right time to keep the flavor fresh.
- Don’t skip the lemon zest; it really elevates the dish.
Storage Pro Tips
Store leftover crispy cauliflower in an airtight container in the refrigerator for up to 3 days. Reheat in the oven to regain that crispy texture. To prevent the bread from getting soggy, store the sauce separately and assemble the sandwich fresh when you’re ready to eat. This will keep everything tasting fresh and delicious!
