Squash, chanterelle and sage flatbread / pizza

My lab hosted a pumpkin themed happy hour on Friday, and it was out of control. We ran a pumpkin carving competition, delivering pumpkins to each lab / group (17 in total) a week in advance and then fanning a wildfire of competing posters from different groups advertising why you should vote for them (in homage to the upcoming election). Then on Friday we made a feast of pumpkin based food, decorated the department in orange and black, ran the ballots for the competition and awarded the trophies (gold-painted gourds on pedestals). The food making was epic: I hacked up 11 butternut squashes with a crappy knife and I've got a blister to prove it. Everything we made contained something squash: pumpkin bruschetta (baguette slices with a smear of baked squash, plus some combination of goat cheese, cranberries, pumpkin seeds, fresh coriander and seasoning), 'squashamole' (dip made with mashed baked squash, lime juice, chopped red onion, ground cumin, chopped coriander and seasoning) with hexagonal multigrain chips (Paul's special request / invention), roasted butternut squash and tofu chunks with rosemary / sage, wild and brown rice mix with toasted pumpkin seeds and fresh coriander, roasted squash seeds with cajun spice, pumpkin chocolate chip cookies, pumpkin cheesecake, pumpkin pie, and pumpkin-white chocolate muffins. We bought the baguettes and the pumpkin pies but we made pretty much everything else from scratch.

So, I couldn't imagine eating another squash after all that, what with the blister and the overexposure. But a lazy Sunday rolled around and S popped up wondering what was for lunch, and I remembered an idea I had of using baked squash instead of tomato sauce on pizza... And also that I had a tub of baked squash left over from happy hour in the fridge, plus a batch of bread mix, the last of the chanterelles and some rosemary and sage from Andrea's yard - seemed like an irresistible plan!

2 orange-sized chunks of dough
1-2 cups of baked squash (peel removed)
1-2 tbsp olive oil
salt+pepper
1 small onion, finely sliced
2-3 cloves garlic, chopped
8 black salty olives, pits removed, torn into quarters
3/4 cup chanterelles, checked for imperfections and torn into large pieces (sliced chestnut mushrooms would be a decent out-of-season substitute)
1 tsp chopped sage leaves
1 tsp chopped rosemary leaves
semolina / corn meal for lining the baking trays
(optional cheese - S is still eating his way through the cheese mountain his mum left behind, so he put some brie and parmesan on his bits)

Heat the oven to 450F. Roll or stretch out the dough as thin as you can - try to get down to ~2 mm thick.  Move the pizza base to a baking tray pre-sprinkled with semolina or coarse corn meal (this quantity is for 2 pizzas).

Mash the baked squash with olive oil, salt and pepper. Smear the bases with the squash mixture, making an uneven covering 2-3 mm thick. Scatter the onion, garlic, olives, chanterelles and herbs over the top, and season / drizzle a wee drop more olive oil over the top.

Put the baking trays in the oven and bake for about 20 minutes / until the crust is crisp and starting to brown around the edges and the toppings are cooked. Remove, let cool for a minute and then eat.


This was a very successful experiment all round. It was a lovely, rich, colourful pizza topping combination that tasted great, and the base came out really crisp. The high speed bread mix worked great as pizza base (which is brilliant news - that stuff is super useful); lining the trays with semolina / cornmeal was much better than using flour; and the squash made a wonderful, very seasonal sauce (less wet than tomato although still moist, perhaps this contributed to the crispness).
