Puffed Cauliflower Gratin


Spring is finally upon us but it will still be a bit of time before local produce is available here in abundance. So, in an effort to mix up my veggie repertoire a bit, I’ve created a light and fluffy cauliflower gratin that can be served with a salad as a light supper or as a side dish with pork chops or chicken. It’s similar enough to mashed potatoes that it makes a great lower carb substitute for spuds, too!


Puffed Cauliflower Gratin

1/2 cup (125 mL) fresh, whole wheat breadcrumbs
2 tbsp (30 mL) melted butter
2 tbsp (30 mL) finely chopped fresh parsley
1 tbsp (15 mL) shredded Asiago cheese (optional)

1 large cauliflower, about 4 lb (2 kg), trimmed
2 tbsp (30 mL) very finely chopped onion
1 tsp (5 mL) minced garlic
1/2 tsp (2 mL) dried thyme leaves
2 tbsp (30 mL) cornstarch
1 cup (250 mL) 2 % milk
3/4 cup (175 mL) shredded Asiago cheese
1/2 tsp (2 mL) salt and pepper
8 egg whites (or 1 carton liquid eggs)

Topping: Toss breadcrumbs with butter; toss with parsley and cheese. Reserve.

Gratin: Cut cauliflower into large chunks; steam for 12 to 15 minutes or until tender. Cool. Purée in batches until smooth using a food processor; transfer to a large bowl.

Preheat oven to 350°F (180°C). Stir onion, garlic and thyme in a microwave-safe bowl. Heat on high for 30 seconds. Whisk the milk with the cornstarch. Stir into the onion mixture. Heat on high for 2 minutes, stirring once. Stir in the cheese, salt and pepper until melted; stir into the cauliflower.

Whip egg whites in a separate bowl until soft peaks form; fold into cauliflower mixture until combined. Transfer to a greased, 8-cup (2 L) deep, round baking dish.

Sprinkle reserved topping over cauliflower mixture. Bake for 35 to 40 minutes or until golden and puffed. Makes 12 servings.

    Mmmmhhh, asiago cheese and cauliflower! A scrumptious looking gratin!



  2. I love cheese and cauliflower! Sounds delicious!

  3. Sounds wonderful. I was looking into potato substitutes and this sounds better than what I came across. Now, if I just don’t tell Andrew it’s made with cauliflower… I just might get away with it. 🙂

    I have a recipe for a cauliflower gratin with goat cheese, I might have to pull that out now. Although, Hubby sure likes his souffles. We’ll see what the market holds on the weekend…
