Everything You Need Lined Up
- 600 grams of potatoes, peeled and cut into 1.5 centimeter cubes. These are gonna be the base of your cheesy foil packet.
- 1 teaspoon of dried thyme leaves if you wanna add a little herby touch.
- Salt and pepper to taste, don't hold back, it's what makes the flavors pop.
- Three quarters cup of thickened or heavy cream. This gives the prawns their creamy sauce that's just divine.
- 30 to 50 grams of butter, more if you like it richer. Butter plus garlic equals dang good stuff.
- One garlic clove minced fine, gotta have that for flavor punch.
- 20 to 24 prawns or shrimp, peeled and deveined ready to dive into the creamy sauce.
- Three quarters to one cup mozzarella or any melting cheese you love to sprinkle on top before sealing.
You also need 2 to 3 bunches of fresh asparagus trimmed and cut in half. The thick ones you can slice vertically so they cook right. Don't forget finely chopped parsley for the garnish, makes it all fresh and pretty.

How It All Comes Together Step by Step
- First, preheat your grill to medium-high heat. It's gotta be ready when we put those foil packets on.
- In a large bowl, toss your potatoes with the dried thyme, salt, and pepper. Make sure they're well coated; each cube should get some love.
- Divide that potato mix into foil packets. Pack 'em tight and seal them good so nothing leaks out on the grill.
- Put the packets on the grill, turning them a couple times over 20 to 25 minutes until potatoes are tender and smelling good.
- While that's happening, melt butter in a saucepan on medium heat, add the minced garlic and sauté until you can smell it, about a minute.
- Add the cream and bring it to a simmer, then toss in those prawns. Cook them just until pink and done, about 5 minutes, careful not to overcook.
- Take the foil packets off the grill, open carefully to not lose steam, stuff the asparagus inside, spoon the creamy garlic prawns over, then sprinkle mozzarella cheese on top. Seal them back tight and grill for 5-10 minutes more until cheese melts. Garnish with parsley before serving.
Quick Tricks That Save Your Time
- Peel and cube your potatoes earlier, toss with a bit of oil and keep in the fridge for a few hours to speed things up.
- Buy pre-peeled and deveined prawns, they save you a ton of prep hassle.
- Use garlic paste if you're in a real rush, just about a teaspoon works fine.
- Wrap your foil packets tightly the first time so you don't have to patch 'em later.
- Double up the cheesy topping, it melts so good and makes every bite gooey and amazing.
Your First Taste After the Wait
You cut into the foil packet and the steam kisses your face like a warm welcome. The cheesy potato shines through with bits of garlic in every cube.
The prawns are silky and soaked in creamy goodness that hits all your senses. That buttery garlic sauce is rich but not heavy, just enough to make you wanna lick the plate.
Asparagus adds a snap of green freshness, balancing the richness perfectly. You take a bite and instantly that smile spreads wide, dang this is comfort food done right.

Making It Last All Week Long
- Store leftovers in airtight containers inside the fridge and try to eat within 3 days cause the creamy sauce is best fresh.
- Reheat gently in the microwave or on the stove over low heat so the prawns stay tender and the cheese doesn't turn rubbery.
- If you wanna freeze, separate the prawns and potatoes, freeze the potatoes and asparagus in foil packs, and keep prawns in a sealed bag to freeze. Thaw in fridge overnight before reheating.
The FAQ Section You Actually Need
- Can I use frozen prawns? Yeah, just thaw them fully before cooking. It helps with even cooking and texture.
- What if I don't have a grill? You can do the foil packets in a preheated oven at 400°F (about 200°C). It works fine but you won't get that grill char flavor.
- Can I swap the cream for something else? You can use half and half or evaporated milk but it won't be as rich and creamy.
- How important is the sealing ring? Super important! Gotta hold the pressure so your dish cooks right and safely.
- What's the float valve for exactly? It tells you when your cooker has pressurized enough and when it's safe to open after the natural release.
- Can I add other veggies? Totally, green beans or bell peppers work well but adjust cooking time if they're crunchier.
