Alpine Mushroom & Swiss Panini
with Asparagus & Garlic Aioli
- Eggs
- Soy
- Wheat
- Milk
Once deemed “lunch food only,” sandwiches (better yet, panini) like this one could not be more dinner-worthy—it features sautéed mushrooms and onion, tangy Dijon mustard, and not one, but TWO types of cheese (Swiss and Monterey Jack) between slices of sourdough and pan-pressed to crispy, golden perfection. On the side, there are potato wedges and garlicky aioli for dipping. Step aside, lunch police!

Cooking Steps
• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut potatoes into ½-inch-thick wedges. Trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!). Halve, peel, and thinly slice onion. • In a small bowl, combine mayonnaise with ¼ tsp garlic powder (½ tsp for 4 servings); season with salt and pepper. (You’ll use the rest of the garlic powder in the next step.)
Trim and discard woody bottom ends from asparagus. (Save potatoes for another use.)
• Toss potatoes on a baking sheet with remaining garlic powder, a drizzle of oil, salt, and pepper. • Roast on top rack until browned and tender, 20-25 minutes.
Swap in asparagus for potatoes; roast until lightly browned and tender, 10-12 minutes.
• Meanwhile, heat a large drizzle of oil in a large pan over medium-high heat. Add mushrooms and season with salt and pepper. Cook, stirring, until lightly browned, 4-5 minutes. TIP: Lower heat and add a splash of water if mushrooms begin to brown too quickly. • Add onion and another drizzle of oil; season with salt and pepper. Cook, stirring, until veggies are browned and tender, 5-7 minutes. • Stir in stock concentrate and 2 TBSP water; cook until water has evaporated and mixture is jammy. • Turn off heat; remove from pan and set aside. Wash out pan.
• Spread half the sourdough slices with mustard, then top with even layers of Swiss (tearing to fit if necessary), mushrooms and onion, and Monterey Jack. • Top with remaining sourdough slices to create sandwiches.
• Melt 1 TBSP butter in pan used for mushrooms and onion over medium heat. (For 4 servings, work in batches or use a second pan, using 1 TBSP butter for each batch.) Add sandwiches and push around in pan until melted butter has absorbed. Cook until bread is golden brown and cheese is slightly melted, 4-6 minutes.
• Add another 1 TBSP butter to pan, then flip sandwiches and push around again until melted butter has absorbed. Cook until bread is golden brown and cheese melts, 4-6 minutes. TIP: If you have a heavy-bottomed pan, place on top of the sandwiches as they cook for a real panini experience! • Halve panini on a diagonal and divide between plates. Serve with potato wedges and garlic aioli on the side for dipping.

- Ease of prep: While tasty, some felt it had more steps and complexity than usual HelloFresh recipes.
- Suggestions: Try reducing onions or cutting them differently; long slices weren't ideal for everyone.
- Leftovers: Reheats well in air fryer or oven, making it a great option for multiple meals.
Reviews from our home cooks
There seemed to be a ton more steps to making this than most recipes we pick, but we did love the result. I just wouldn't do it very often because of the complexity/time involved.
Got this for my hubs even tho I don't like mushrooms or sourdough bread but of course I had to taste test it, and OmG it was amazingly delicious!! Who would have thought?!?!
Easy to make and delicious, easy to reheat in air fryer or oven
Looooved this dish. Always impressed with the quality of bread from HF!
Every ingredient was pretty great, just not sure about the amount of onions needed for this kind of meal, seems like a lot or maybe a different onion/cuts of the onion instead of long slices.
