I first discovered this recipe during a particularly hectic week when I needed something that would feed my family well without requiring too much fuss. What started as a simple "throw everything in a dish and bake it" experiment turned into one of our most requested meals. The beauty lies in its simplicity - tender penne pasta gets coated in a creamy sauce, then layered with sautéed bell peppers and mushrooms before being topped with a generous blanket of melted cheese. The vegetables add both nutrition and gorgeous color, while the cheese creates that irresistible golden top that makes everyone's mouth water. Each bite delivers the perfect balance of creamy, cheesy comfort with the fresh crunch of vegetables. It's the kind of dish that makes your house smell like home and brings everyone to the dinner table with genuine excitement.
Why I love this recipe
What I absolutely adore about this recipe is how it transforms simple, everyday ingredients into something that feels special and indulgent. There's something deeply satisfying about pulling a bubbling, golden casserole from the oven and watching everyone's faces light up. It's comfort food at its finest, but with enough vegetables to make me feel good about serving it to my family. The recipe is incredibly forgiving - if you don't have red peppers, use green ones. No mushrooms? Add some zucchini or broccoli instead. The cheese ties everything together beautifully, creating a dish that's both sophisticated enough for company and simple enough for a Tuesday night. Plus, it makes fantastic leftovers, which means less work for me during the week. It's become my go-to recipe when I want to show love through food without spending hours in the kitchen.
What You Need From Your Kitchen
- Penne pasta: cook until al dente according to package directions
- Mozzarella cheese: shred fresh for best melting results
- Bell peppers: slice into strips and sauté until tender
- Mushrooms: slice thick and cook until golden
- Heavy cream: simmer with vegetables to create sauce
- Parmesan cheese: grate fresh and sprinkle on top before baking
Let's Make These Together
- Prepare all ingredients
- Start by gathering all your ingredients and prepping the vegetables. Cook the pasta until al dente, then drain and set aside. Slice your bell peppers into strips and mushrooms into thick pieces. Having everything ready makes the cooking process smooth and enjoyable.
- Sauté the vegetables
- Heat olive oil in a large skillet over medium heat. Add the minced garlic first, followed by the bell peppers and mushrooms. Cook them until they're tender and slightly caramelized, which takes about 8-10 minutes. The vegetables should be soft but still have a bit of bite to them.
- Create the creamy sauce
- Pour the heavy cream into the skillet with your sautéed vegetables. Let it simmer gently for 2-3 minutes, stirring occasionally. Season with salt and pepper to taste. The cream will thicken slightly and coat the vegetables beautifully.
- Assemble and bake
- Mix the cooked pasta with your creamy vegetable mixture, then transfer everything to a greased baking dish. Top generously with mozzarella and Parmesan cheese. Bake at 375°F for 25-30 minutes until the cheese is bubbly and golden on top.

Switch Things Up
I remember the first time I made this dish, I was skeptical about whether my kids would eat all those vegetables. But something magical happens when you cover anything with melted cheese! They devoured it and asked for seconds. Now it's become our Sunday meal prep staple. I love how versatile it is - sometimes I throw in whatever vegetables are lurking in my fridge. Zucchini, broccoli, even leftover roasted vegetables work beautifully. The key is not to overthink it and just let the cheese work its magic.
Perfect Pairings
This hearty pasta bake pairs wonderfully with a crisp Caesar salad and some crusty garlic bread for soaking up any extra cheese sauce. For wine lovers, a medium-bodied red like Chianti or a crisp white wine like Pinot Grigio complements the rich flavors perfectly. If you're serving this for a casual dinner party, consider adding some roasted cherry tomatoes on the side and a simple arugula salad with lemon vinaigrette to cut through the richness.
