Forget bland cauliflower. This is the plate that makes you hover over the pan and “taste test” half the batch before it reaches the table. Smoky prosciutto, briny capers, and toasted almonds team up to turn humble florets into a crispy, salty, buttery show-off.
It’s fast, it’s keto, and it hits those crunchy, umami notes like a cheat meal—without the guilt. Want a dish that feels restaurant-level but takes less time than scrolling for one? Pull up a sheet pan.
What Makes This Recipe Awesome
- Big flavor, low carbs: Cauliflower stays keto-friendly while prosciutto and capers pile on depth and saltiness.
Almonds add crunch. It’s snackable and smart.

- Texture overload (in a good way): Crispy edges, silky prosciutto ribbons, and nutty crunch keep every bite interesting.
No boring bites allowed.

Shopping List – Ingredients
- 1 large head cauliflower, cut into bite-size florets (about 6–7 cups)
- 3 tablespoons avocado oil (or olive oil)
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika (optional but recommended)
- 1/4 teaspoon red pepper flakes (optional heat)
- 3 ounces prosciutto, sliced into ribbons
- 3 tablespoons capers, drained and patted dry
- 1/3 cup sliced or slivered almonds
- 2 tablespoons butter (or ghee), for finishing
- 1 tablespoon lemon juice, plus zest of 1/2 lemon
- 2 tablespoons chopped fresh parsley (or basil)
- Optional garnish: shaved Parmesan, extra lemon wedges
Step-by-Step Instructions
- Preheat the oven: Set to 425°F (220°C).
Place a large sheet pan inside to heat up. A hot pan = crispy cauliflower. Science!
- Prep the cauliflower: Trim leaves and core, then break into uniform florets.
Smaller florets crisp faster, larger ones stay tender. Pick your adventure.
- Season: In a bowl, toss florets with avocado oil, salt, pepper, smoked paprika, and red pepper flakes if using.
- Roast round one: Carefully remove the hot sheet pan, spread cauliflower in a single layer (flat sides down), and roast for 18–20 minutes until edges begin browning.
- Toast the almonds: While cauliflower roasts, lightly toast almonds in a dry skillet over medium heat for 2–3 minutes until golden and fragrant. Transfer to a plate.
- Crisp the prosciutto: In the same skillet, cook prosciutto ribbons for 1–2 minutes until just crisp.
Remove. Add the capers to the rendered fat and cook 60–90 seconds until some pop and turn golden. Set aside.
- Roast round two: Flip cauliflower, scatter butter in small pieces over the florets, and roast another 6–8 minutes.
Butter browns, flavor skyrockets.
- Finish: Transfer cauliflower to a serving bowl. Add prosciutto, capers, almonds, lemon zest, and parsley. Toss with lemon juice.
Taste and adjust salt and pepper.
- Serve: Finish with shaved Parmesan if desired. Hot tip: a squeeze of extra lemon at the table makes it pop.
Preservation Guide
- Refrigerate: Store leftovers in an airtight container for up to 3 days. Keep garnishes (Parmesan, extra herbs) separate if possible.
- Reheat: Use a 400°F (205°C) oven or air fryer for 5–7 minutes to restore crispness.
Microwave works, but you’ll lose some crunch, FYI.
- Freezing: Not ideal. Cauliflower texture gets mushy and capers go sad. If you must, freeze without prosciutto and almonds, then add fresh when reheating.
- Make-ahead: Roast cauliflower up to a day ahead.
Re-crisp in a hot oven and finish with fresh prosciutto, capers, almonds, and lemon.
Health Benefits
- Low carb, high satisfaction: Cauliflower supplies volume and fiber without the carb crash. Perfect for keto or low-glycemic goals.
- Healthy fats: Avocado oil, almonds, and butter provide satiating fats that keep energy stable and cravings quiet.
- Micronutrient-rich: Cauliflower brings vitamin C, K, and choline; almonds add vitamin E and magnesium. Prosciutto and capers contribute flavor with minimal carbs.
- Protein boost: Prosciutto and almonds help round out the plate.
Add a fried egg or grilled protein to hit your macros with ease.
- Antioxidants and polyphenols: Herbs, lemon zest, and almonds support overall wellness while making everything taste better—yes, you’re allowed to enjoy health food.
Common Mistakes to Avoid
- Overcrowding the pan: If the florets touch or pile up, they steam. Use two pans or roast in batches for crisp, caramelized edges.
- Skipping the preheated sheet pan: Starting on a hot surface jump-starts browning. Cold pan = meh results.
- Not drying capers: Wet capers won’t crisp and can splatter.
Pat them dry before sautéing.
- Adding lemon too early: Acid can soften the cauliflower’s crisp edges if added before roasting. Finish with it at the end.
- Burning the almonds: They go from toasty to tragic fast. Stir and watch closely.
Recipe Variations
- Garlic-parm upgrade: Add 2 minced garlic cloves in the last 5 minutes of roasting and finish with 1/4 cup finely grated Parmesan.
- Chili-crunch twist: Swap red pepper flakes for a spoon of chili crisp at the end for heat plus texture (check labels for carbs).
- Herb-forward: Use basil and mint instead of parsley, and finish with a drizzle of high-quality olive oil.
- Pistachio swap: Replace almonds with chopped pistachios for a slightly sweeter, vivid-green crunch.
- Protein-plus: Top with a 6-minute jammy egg, grilled shrimp, or shredded rotisserie chicken to make it a full meal.
- Dairy-free: Use ghee or skip butter and add 1 extra tablespoon avocado oil.
Still rich, still awesome.
- Lemon-caper sauce: Whisk 2 tablespoons olive oil, 1 tablespoon lemon juice, 1 teaspoon Dijon, and 1 tablespoon chopped capers. Drizzle before serving.
FAQ
Is prosciutto keto-friendly?
Yes. Prosciutto is essentially zero-carb and high in protein and fat, making it keto-friendly.
Choose a brand without added sugars for best results.
Can I use frozen cauliflower?
You can, but expect less crispiness. Roast from frozen on a very hot pan, give it extra time, and don’t crowd. Fresh yields the best texture IMO.
What can I substitute for prosciutto?
Crispy bacon or pancetta works beautifully.
For a non-pork option, use turkey bacon or skip meat and add extra almonds plus a sprinkle of Parmesan.
How do I prevent soggy cauliflower?
Dry the florets thoroughly, use high heat, preheat the pan, don’t overcrowd, and flip midway. Airflow is everything.
Are capers necessary?
They’re the briny spark that balances the richness. If you don’t have them, try chopped green olives or a splash of olive brine at the end.
What’s the best oil for roasting?
Avocado oil handles high heat well and stays neutral.
Olive oil also works; just watch for smoking at higher temps.
Can I make this nut-free?
Yes. Use toasted pumpkin seeds or sunflower seeds for crunch. Same vibe, no nuts.
