Caramelized onions and burst cherry tomatoes roasted with a whole garlic bulb, then tossed with creamy vegan cream cheese, chili oil, and rigatoni for an effortless baked pasta that looks and tastes incredible. One tray, minimal cleanup, maximum flavor.
Prep the baking tray. Preheat oven to 400°F (200°C). Add the sliced onions to a large baking tray. Drizzle with olive oil and season with smoked paprika, oregano, salt, and pepper. Toss everything together until well coated.
Add tomatoes and garlic. Scatter the cherry tomatoes over the onions. Slice the top off the garlic bulb to expose the cloves and nestle it in the center of the tray. Cover tightly with aluminum foil.
Roast. Bake covered for 40 to 45 minutes until the onions are deeply caramelized and the tomatoes have burst and released their juices.
Cook the pasta. While the tray roasts, cook the rigatoni in salted boiling water according to package directions until al dente. Reserve ½ cup of pasta water before draining.
Make the sauce. Remove the tray from the oven. Squeeze the roasted garlic cloves out of the bulb into the tray. Add the vegan cream cheese, chili oil, and fresh basil. Stir everything together until the cream cheese melts into a creamy sauce.
Combine and serve. Add the cooked rigatoni and reserved pasta water to the tray. Toss everything together until the pasta is evenly coated in the creamy sauce. Top with vegan parmesan, garnish with extra basil, and serve straight from the tray.
