Mushroom And Sweet Onion Gnocchi Casserole

Puffy gnocchi in a savoury, creamy sauce laden with mushrooms and sweet onions makes for a nice change from tomato-pasta casseroles and is far better than takeout (which can be tempting on a rushed day). Having a few dishes of this comfort-food meal tucked in the freezer for a simple reheat can save the day when the holiday preparations are in full swing. If you prefer to use one larger casserole dish, use an 8-cup (2-L) shallow dish and allow 24 to 36 hours to thaw (or defrost in the microwave); the reheating time will be the same. You can also double the recipe easily: just sauté the mushrooms in two separate batches. Serve a crispy, vinaigrette-dressed green salad on the side.

Ingredients

3 tbsp (45 mL) olive oil, divided
2 tbsp (30 mL) butter, divided
1 lb (455 g) cremini mushrooms, sliced
Salt and freshly ground pepper
1 sweet onion, thinly sliced
1 tsp (5 mL) dried rosemary, crumbled
1 lb (455 g) gnocchi
3 cloves garlic, minced
½ cup (125 mL) dry white wine
2 tbsp (30 mL) all-purpose flour
2 cups (500 mL) 10% cream, heated
2 tbsp (30 mL) chopped fresh parsley
Additional 10% cream or milk, warmed
Freshly grated Parmesan cheese

Directions:
Heat 2 tbsp (30 mL) of the oil and 1 tbsp (15 mL) of the butter in a large skillet over medium-high heat until sizzling. Add mushrooms, ½ tsp (2 mL) salt and ¼ tsp (1 mL) pepper; sauté for about 10 minutes or until mushrooms have released their liquid and are lightly browned. Transfer to a large bowl.

Add remaining butter to skillet and melt over medium heat. Add onion, rosemary and ¼ tsp (1 mL) salt. Cook, stirring often, for about 5 minutes or until softened. Reduce heat to medium- low and cook, stirring often, for about 20 minutes or until soft and golden.

Meanwhile, cook gnocchi in a large pot of boiling salted water, stirring often, for about 3 to 4 minutes or just until they rise to the surface (do not overcook). Using a metal sieve, scoop gnocchi out of water, draining well, and transfer to a large bowl, reserving cooking water. Add remaining 1 tbsp (15 mL) oil to gnocchi and stir gently to coat. Set aside to cool.

Add garlic to onion and cook, stirring, for 3 minutes or until fragrant. Increase heat to medium-high and pour in wine. Bring to a boil, scraping up any brown bits in pan. Boil for 2 minutes or until reduced by about half.

Whisk flour into cream and gradually pour into skillet, while stirring. Cook, stirring, for about 5 minutes or until slightly thickened. Season to taste with salt and pepper. Pour into bowl with mushrooms and let cool.

Pour mushroom sauce over gnocchi in bowl and stir gently to coat. Add reserved cooking water, a little at a time, to moisten as desired. You want the gnocchi to be quite saucy as the liquid will be absorbed upon baking. Stir in parsley.

Spoon gnocchi into three or four 2- to 4-cup (500-mL to 1-L) shallow baking dishes. Cover tightly with plastic wrap then place dishes in freezer bags or cover with foil. Freeze for up to 1 month.

To serve, let gnocchi thaw in refrigerator for at least 12 hours or for up to 2 days (alternatively, microwave baking dishes, one at a time, loosely covered with plastic wrap, on defrost/ 50% power, stirring every 2 minutes, until thawed, being careful not to let them heat).

Preheat oven to 350°F (180°C).

Remove plastic wrap and cover baking dishes with foil. Bake gnocchi for about 45 minutes or until hot and bubbling around the edges. Uncover and bake for 10 to 15 minutes to brown top lightly.

Serve with a little warm cream to stir in and thin sauce, as desired, then sprinkle with Parmesan.
