Instructions To Make Mary Berry’s Garlic Mushroom Penne Gratin

Let’s walk through this recipe step-by-step. Take your time with each one-this dish is all about layering flavors and textures beautifully.

1. Preheat The Oven

Set your oven to 200°C (180°C fan) / 400°F / Gas Mark 6. Get your baking dish ready-no need to grease it, as the creamy sauce will do that job.

2. Cook The Penne

Bring a large pot of salted water to a boil. Add the penne and cook until just al dente-about 1-2 minutes less than the package instructions. Drain and set aside. Toss with a drizzle of olive oil to prevent sticking.

3. Sauté The Mushrooms And Garlic

In your frying pan, heat the butter and a splash of olive oil over medium-high heat. Add the sliced mushrooms and sauté until they release their moisture and begin to brown (around 8-10 minutes). Add the minced garlic and cook for another minute, stirring frequently to avoid burning.

4. Make The Creamy Sauce

Sprinkle the flour over the mushrooms and stir well to coat evenly-cook for 1-2 minutes to eliminate the raw flour taste. Slowly pour in the milk, stirring constantly to prevent lumps. Once thickened, stir in the double cream and season with salt, black pepper, and a pinch of nutmeg if using. Let the sauce simmer gently for a few minutes until velvety.

5. Combine Pasta And Sauce

Add the cooked penne to the creamy mushroom mixture and stir gently to coat everything in the sauce. At this stage, you could taste and adjust the seasoning if needed.

6. Assemble The Gratin

Pour the mixture into your ovenproof baking dish. In a small bowl, combine the breadcrumbs, grated Parmesan, and half the Cheddar or Gruyère. Sprinkle this mix generously over the top of the pasta.

7. Bake To Golden Perfection

Place the dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling. If the top isn’t crisp enough for your liking, finish under the grill (broiler) for 2-3 minutes.

8. Garnish And Serve

Once out of the oven, let the gratin rest for a few minutes. Sprinkle with chopped parsley before serving for a touch of color and freshness.

Tips And Tricks

Here are some insider tips to make your Garlic Mushroom Penne Gratin turn out beautifully every time:

  • Don’t overcook the pasta: Remember, it will continue cooking in the oven. Undercooking slightly ensures it stays pleasantly firm.
  • Use a mix of mushrooms: For a deeper umami flavor, try combining chestnut, shiitake, and oyster mushrooms.
  • Make it ahead: Assemble the gratin up to the point of baking, then cover and refrigerate for up to 24 hours. Bake straight from the fridge, adding 5-10 minutes to the cooking time.
  • Go gluten-free: Use gluten-free penne and swap the plain flour with a gluten-free blend.
  • Add a protein boost: Stir in cooked chicken, pancetta, or even crispy tofu for variation.
  • Enhance the crust: A few dots of butter on top of the breadcrumb mixture before baking can help it crisp up and turn extra golden.

Mary Berry’s Garlic Mushroom Penne Gratin is the kind of dish that warms your kitchen and your soul. It’s simple yet luxurious, packed with rich, earthy flavors from mushrooms and garlic, and made indulgent with its creamy sauce and bubbling cheesy crust.

Storing Leftovers

One of the biggest perks of this gratin is how well it holds up the next day. In fact, some might say it’s even better after the flavors have had time to mingle overnight.

Refrigeration

  • Storage Time: Leftovers keep beautifully in the fridge for up to 3-4 days.
  • Container: Use an airtight container to keep it fresh, or cover the original baking dish tightly with foil or cling wrap.
  • Tip: To prevent it from drying out, splash a tablespoon of milk or cream over the surface before reheating-it’ll help rehydrate the sauce.

Freezing

  • Yes, You Can Freeze It: While the texture of the sauce might alter slightly due to the dairy, it freezes surprisingly well.
  • How To Freeze: Let the gratin cool completely, portion into airtight containers or wrap tightly in foil and plastic wrap. Label with the date.
  • Shelf Life: It’ll keep in the freezer for up to 2 months.
  • To Reheat: Thaw overnight in the fridge, then bake at 180°C (350°F) until bubbling hot-usually around 20-25 minutes. Add fresh cheese on top before baking for a just-made feel.
