Each half-pizza serving delivers 437 kcal, 17.4g protein, and 57g carbs with 4.3g fibre — higher in calories than a typical frozen pizza slice due to its generous, topping-rich Sicilian style. It is free from dairy and suitable for vegans, making it one of the few restaurant-quality vegan frozen pizzas available in UK supermarkets.

Macronutrient Breakdown
NUTRITIONIST'S INSIGHT
At 437 kcal per half-pizza, this is a substantial meal that fits comfortably within a single-meal allowance for most adults. The sourdough lievito madre base has a moderately lower glycaemic impact than standard white-flour pizza crusts due to partial fermentation breaking down some starches and phytic acid. The vegetable toppings — spinach, olives, capers, and onion — contribute meaningful micronutrients including iron, polyphenols, and vitamin K, though the 960mg sodium per serving (2.4g salt) is worth noting for those watching blood pressure.
Myth Busters
MYTH #1: Frozen pizza is always ultra-processed junk food
TRUTH: Crosta & Mollica Siciliana uses a short, recognisable ingredient list — wheat flour, water, vegetables, olive oil, and naturally fermented mother yeast — placing it closer to artisan pizza than to standard frozen ultra-processed products.

MYTH #2: Pizza always causes a rapid blood sugar spike
TRUTH: Pizza's combined fat, protein, and fibre content significantly slows gastric emptying, creating a slower and more prolonged glucose response compared to eating plain refined carbohydrates alone. Sourdough fermentation further lowers the glycaemic index of the crust. Glycemic index of pizza: cheese topping, thin crust, frozen, cooked; Is Pizza High Glycemic?

MYTH #3: Vegan pizzas are low in calories
TRUTH: Vegan frozen pizzas can be just as calorie-dense as cheese-topped varieties. This Siciliana pizza delivers 437 kcal per serving primarily from its thick sourdough crust and generous olive oil drizzle, not from cheese. Crosta & Mollica Siciliana Sourdough Pizza – Official Product Page
MYTH #4: Sourdough pizza crust has a low glycaemic index
TRUTH: Sourdough fermentation does reduce the GI of pizza bases compared to yeast-leavened versions, but a sourdough pizza crust still sits in the moderate-to-high GI range (around 55–70), not low. Toppings with fat and fibre help blunt the overall meal response. Glycemic index of pizza: cheese topping, thin crust, frozen, cooked; Is Pizza High Glycemic?

NutriScore by Health Goals
| Health Goal | NutriScore | Why This Score? |
|---|---|---|
| weight_loss |  | At 437 kcal per serving this is filling and satisfying, but the calorie density is high enough that portion control matters. The 17g protein and 4g fibre support satiety, making it easier to stop at one serving. Crosta & Mollica Siciliana Sourdough Pizza – Official Product Page |
| muscle_building |  | 17.4g protein per serving is a respectable contribution for a vegan meal. Combined with the 57g carbs for post-workout glycogen replenishment, this can fit a muscle-building diet, though pairing with a protein-rich side would bring it closer to optimal.

| heart_health | | The extra virgin olive oil, Taggiasca olives, and vegetables provide heart-healthy monounsaturated fats and polyphenols. However, 960mg sodium per serving represents about 40% of the UK daily recommended limit, which is a meaningful concern for cardiovascular health.

| diabetes_management |  | 57g carbohydrates per serving is a significant glucose load even with the sourdough base and 4.3g fibre. The fat content moderates the spike, but individuals managing blood sugar should limit portions, pair with a salad, and monitor their response closely.

Typical Glucose Response Curve
**Not medical advice**
How to flatten the spike
- Keep the portion to the labelled serving and avoid eating straight from the bag or tray.
- Pair it with a protein or fibre source, such as Greek yogurt, eggs, lentils, beans, salad, or edamame, when you want steadier appetite and glucose control.
- Avoid pairing it with sugary drinks; choose water, unsweetened tea, or coffee so the snack does not become a larger sugar load.
Cultural Significance
Sicilian pizza — known as sfincione in its native form — has roots stretching back centuries in Palermo, where a thick, pillowy dough topped with tomato, onion, anchovies (or in vegetarian variants, olives and capers), and fragrant oregano was sold by street vendors. Unlike Neapolitan pizza with its thin charred base, Sicilian-style pizza is characterised by its thick, airy crust baked in rectangular trays, absorbing the sauce into a deeply flavourful bread. Crosta & Mollica's Siciliana takes inspiration from this tradition — using slow-fermented lievito madre dough, Trapanese capers, PGI Tropea red onion, and Taggiasca olives — while adapting it to a round frozen format for the UK market. The brand, founded in London with Italian roots, focuses on authentic regional Italian ingredients and has introduced many UK consumers to the distinctive flavours of Sicilian produce.

Frequently Asked Questions
Is Crosta Mollica Siciliana pizza vegan?
Yes, the Siciliana Sourdough Pizza is certified vegan. It contains no dairy or animal products. The toppings are entirely plant-based — spinach, Taggiasca olives, Tropea red onion, capers, garlic, and tomato. It is prepared in a facility that handles milk, so those with severe dairy allergies should exercise caution.
How many calories are in a whole Crosta Mollica Siciliana pizza?
The full 405g pizza contains approximately 874 kcal. The official serving size is half the pizza (around 202g) at 437 kcal per serving.
Does sourdough pizza have a lower glycaemic index than regular pizza?
Yes, to a moderate degree. The lactic acid produced during sourdough fermentation slows starch digestion, resulting in a somewhat lower and more gradual blood sugar rise compared to standard yeast-leavened pizza dough. However, it is still a carbohydrate-dense food, so portion size remains important.
Is Crosta Mollica Siciliana pizza high in sodium?
Yes. Each half-pizza serving contains 960mg of sodium (2.4g salt), which is about 40% of the UK adult recommended daily maximum of 6g. Those managing blood pressure or on a low-sodium diet should consider having a smaller portion or pairing it with low-sodium foods throughout the day.

The Siciliana Sourdough Pizza is available at Tesco stores and online at Tesco.com. Other Crosta & Mollica pizzas are also stocked at Sainsbury's and Morrisons, though specific variety availability varies by retailer.
Can I cook Crosta Mollica Siciliana pizza from frozen?
Yes, it is designed to be cooked from frozen. Typical instructions are to preheat the oven to 220°C (200°C fan) and bake for 12–14 minutes directly on the oven shelf or on a baking tray until the crust is golden and cooked through. Always check the packaging for exact cooking instructions.
