Mad for mushrooms? Fan of fungi? Totally taken with toadstools? If you nodded emphatically while reading along, we’ve got the perfect dish for you. Italian-seasoned portobellos are roasted until tender, flipped, and filled with marinara sauce and a mound of melty cheeses. They’re then broiled to bubbly, melty perfection and perched atop spaghetti. A sprinkle of toasty, buttery panko ties everything together, adding carby crunch to this ’shroom-centric soirée.
Produced in a facility that processes milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybean.

• Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees. Bring a large pot of salted water to a boil. Line a baking sheet with foil (line 2 sheets for 4). Wash and dry produce. • Trim any large stems from portobello mushrooms if necessary.
• Drizzle both sides of each mushroom with olive oil; rub to evenly coat. Season all over with 1 tsp Italian Seasoning (2 tsp for 4 servings), salt, and pepper. (You’ll use the remaining Italian Seasoning later.) Arrange mushrooms gill sides down on prepared baking sheet. (Divide between both prepared sheets for 4; roast on top and middle racks.) • Roast on top rack until tender, 14-16 minutes.
• Once water is boiling, add spaghetti to pot. Cook until al dente, 9-11 minutes. • Reserve ½ cup pasta cooking water, then drain.
• Meanwhile, melt 1 TBSP butter (2 TBSP for 4 servings) in a large pan over medium-high heat. Add panko and half the garlic powder. Cook, stirring, until golden brown, 3-5 minutes. Season with salt and pepper. Turn off heat; transfer to a small bowl. Wipe out pan. • Return same pan to medium heat. Pour in marinara, remaining Italian Seasoning, remaining garlic powder, stock concentrate, and 1 tsp sugar (2 tsp for 4). Bring to a simmer; cook, stirring occasionally, until warmed through, 2-3 minutes. • Turn off heat. Reserve ¼ cup marinara (½ cup for 4).
• Once mushrooms are tender, remove sheet from oven; flip mushrooms over on sheet. Heat broiler to high. • Stir drained spaghetti and 1 TBSP butter into sauce. • Spoon reserved marinara into mushrooms, then mound evenly with Italian cheese. • Broil until cheese is melted and lightly browned, 2-4 minutes. TIP: Watch carefully to avoid burning.
• If needed, stir reserved pasta cooking water a splash at a time into pan with spaghetti over low heat until pasta is thoroughly coated in sauce. Taste and season with salt and pepper. • Divide spaghetti between plates and top with cheesy mushrooms. Sprinkle with crispy breadcrumbs and serve.
