This oven baked 5-ingredient garlic herb cheese pasta is the kind of cozy, no-fuss dinner my husband asked for twice in one week—and I honestly couldn’t believe how simple it was to pull together. Everything bakes in one glass dish, and you end up with tender rigatoni wrapped in a creamy, garlicky herb cheese sauce and bright green spinach. It feels like something you’d order at a little family Italian spot, but it’s made from pantry staples and a bag of spinach. It’s perfect for busy nights when you still want to put something warm and homemade on the table without hovering over the stove.
Serve this pasta straight from the glass baking dish with a big spoon so everyone can scoop out those cheesy, creamy pockets of rigatoni. It pairs really well with a simple green salad dressed with olive oil and vinegar, or some roasted broccoli if you want more veggies on the plate. Warm garlic bread or a sliced baguette is great for soaking up the extra sauce. For adults, a glass of chilled white wine or sparkling water with lemon works nicely, and for kids, I usually pour milk or apple juice and put out a little bowl of baby carrots or cucumber slices for crunch.
Oven Baked 5-Ingredient Garlic Herb Cheese Pasta
Servings: 6

Ingredients
12 oz dry rigatoni pasta
1 (8 oz) block cream cheese, softened
1 (5 to 6 oz) package garlic & herb soft cheese spread (such as Boursin or similar)
3 cups milk (whole or 2%)
5 oz fresh baby spinach, roughly chopped
1 tsp salt
1/2 tsp black pepper
Nonstick cooking spray or 1 tbsp olive oil (for greasing the baking dish)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass baking dish with nonstick cooking spray or a little olive oil.
Add the dry rigatoni to the prepared glass baking dish and spread it out into an even layer. It will look like too much pasta at first, but it will soften and soak up the sauce as it bakes.
In a large mixing bowl, whisk together the softened cream cheese, garlic & herb cheese spread, milk, salt, and black pepper until mostly smooth. A few small bits of cheese are fine; they’ll melt in the oven. If the cream cheese is very firm, you can microwave it for 15–20 seconds to soften before mixing.
Pour the cheese and milk mixture evenly over the dry rigatoni in the baking dish. Use a spoon to gently stir and nudge the pasta around so that most of the noodles are coated and submerged in the liquid. This helps everything cook evenly.
Sprinkle the chopped fresh spinach evenly over the top of the pasta. Use the back of a spoon to gently press it down into the liquid. It will look like a lot of spinach, but it cooks down and gives the pasta that pretty bright green color and a fresh flavor.
Cover the glass baking dish tightly with foil, making sure to crimp the edges so steam doesn’t escape. This step is important so the pasta can cook through in the sauce without drying out.
Bake the covered dish on the center rack for 35 minutes. Carefully remove the foil (watch for hot steam), give the pasta a gentle stir to loosen any noodles that are sticking, and check the amount of liquid. The pasta should be mostly tender but still a bit firm in the center, and the sauce will look loose.
Return the dish to the oven, uncovered, and bake for another 10–15 minutes, or until the rigatoni is tender and the sauce has thickened into a creamy coating. The top may get a few golden spots, which adds nice flavor.
Once done, remove the baking dish from the oven and let the pasta rest for 5–10 minutes. The sauce will continue to thicken as it cools slightly, making it easier to scoop clean portions with a serving spatula, just like in those cozy casserole photos.
Taste and adjust the seasoning with a little more salt and pepper if needed before serving. Scoop generous portions straight from the glass dish, making sure to get plenty of spinach and creamy sauce in each serving.
Variations & Tips
To keep this recipe truly simple, I stick to 5 core ingredients: rigatoni, cream cheese, garlic & herb cheese, milk, and spinach. The salt, pepper, and oil are just everyday helpers. For picky eaters, you can finely chop the spinach so it blends into the sauce, or swap it for a milder veggie like finely chopped baby kale or thawed, squeezed-dry frozen spinach. If your family prefers extra cheesy pasta, sprinkle 1 to 1 1/2 cups shredded mozzarella or Italian blend cheese over the top during the last 10 minutes of baking for a browned, bubbly crust. You can also use different pasta shapes like penne or ziti; just keep the amount the same and check for doneness, adding a splash more milk if it seems dry. For added protein, stir in cooked, chopped chicken or browned Italian sausage after the first 35 minutes of baking, then finish uncovered. To lighten it up a bit, use 1/3-less-fat cream cheese and 2% milk; the sauce will still be creamy, just a touch less rich. Food safety tips: Always use pasteurized dairy products, and keep the cream cheese and garlic herb cheese refrigerated until you’re ready to mix the sauce. If you add meat, make sure it’s fully cooked before stirring it into the pasta, and avoid letting the finished casserole sit out at room temperature for more than 2 hours. Refrigerate leftovers in a covered container and eat within 3–4 days, reheating until hot and steaming in the center before serving.
