We had a fun debate over cheese when I made this Easy & Cheesy Baked Spaghetti. David thought the shredded sharp cheddar cheese was enough, but I went for both the Italian cheese blend and sharp cheddar. Spoiler: it made the dish a winner, and the whole thing disappeared in no time.


Cooking the spaghetti just under the package directions keeps it from getting mushy. This way, it holds its shape and absorbs the marinara sauce without losing texture, leading to a better dish overall.

Ingredients in Easy & Cheesy Baked Spaghetti

This dish is all about balance—rich beef, melty cheese, and hearty spaghetti come together for a satisfying meal. Here’s what you need to make it happen:

  • Olive Oil: Helps brown the beef and onions, adding depth to the flavor.
  • Ground Beef: Provides a hearty protein base. I recommend using 93% lean for the right balance of flavor and fat.
  • Yellow Onion: Adds savory sweetness and depth. Chop it finely for even cooking.
  • Italian Seasoning: Brings that classic Italian flavor to the dish. It’s a blend of herbs that works wonders here.
  • Red Pepper Flakes: Adds a bit of heat. Adjust the amount based on your spice preference.
  • Kosher Salt & Black Pepper: Essential for seasoning. Always taste as you go to get it just right.
  • Garlic Paste: Packs a punch of flavor.
  • Brown Sugar: Balances the acidity of the marinara sauce. Just a tablespoon does the trick.
  • Marinara Sauce: The flavorful base that ties everything together.
  • Spaghetti: The star of the show! Cook it just under the package directions for better texture.
  • Italian Cheese Blend: Melty and creamy; it forms that golden crust on top.
  • Sharp Cheddar Cheese: Adds richness and enhances the cheesy goodness.
  • Parmesan Cheese: For an extra cheesy finish. Use fresh grated for the best results.

How to Make Easy & Cheesy Baked Spaghetti

This dish comes together in about 45 minutes, making it a perfect option for busy weeknights. Once you see how easy it is to whip this up, it’ll become a staple at your dinner table.

  1. Preheat Oven: Set your oven to 375°F. Make sure it’s nice and hot when you’re ready to cook. This helps the cheese melt and get that golden edge.

  2. Cook Spaghetti: Bring a pot of salted water to a simmer. Cook the spaghetti for about 8-9 minutes, or until it’s just underdone. You want it to be firm; it’ll finish cooking in the dish.

  3. Brown Beef: In a large dutch oven, heat olive oil over medium-high heat. Add ground beef and break it up with a wooden spoon. Cook until it’s browned and slightly crisp.

  4. Add Onions: Toss in chopped medium yellow onion and cook for another 3-4 minutes. Stir often until the onion is tender and translucent. This adds a nice sweetness to your beef mixture.

  5. Mix Sauce: Stir in Italian seasoning, red pepper flakes, and season with Kosher salt and black pepper. Add garlic paste, brown sugar, and marinara sauce. Let the sauce simmer for about 2-3 minutes, stirring occasionally until everything’s well combined.

  6. Combine Spaghetti: Add the drained spaghetti to the meat sauce and toss until it’s fully coated. You want every strand to soak up that flavorful sauce.

  7. Transfer to Dish: Carefully pour the spaghetti mixture into a 9×13-inch baking dish. Spread it evenly with a utensil, ensuring it’s nicely packed.

  8. Add Cheese: In a bowl, mix shredded Italian cheese blend and grated parmesan cheese. Sprinkle this cheesy goodness over the top of the spaghetti.

  9. Cook: Place the dish in the oven and cook until the cheese is bubbly and just starting to brown. If you want an extra crispy top, broil for 1-2 minutes. Let it cool for 5-7 minutes before serving.

Enjoy this meal with a simple salad or some garlic bread for a complete dinner!

Keeping Leftovers Fresh

You can store any leftovers in an airtight container in the fridge for up to three days. If you want to freeze it, it’ll hold up for about three months. Just make sure to let it cool completely before sealing it up, so you don’t trap any moisture inside.

For reheating, I recommend putting it in the oven at 350°F. Cover it with foil to keep it from drying out, and heat until warmed through. If it feels a bit dry, add a splash of marinara sauce before reheating to keep it nice and moist.
