High-Protein Baked Spaghetti—Ultra Easy!

High-Protein Baked Spaghetti—Ultra Easy!


If you’ve ever wanted to eat lasagna with some extra protein, this baked spaghetti hits that perfect cheesy, cozy sweet spot. It’s creamy, cheesy, meaty, and bubbling with bold flavor. It packs a whopping 56 grams of protein and 834 calories per serving. 

And when you’re working with a really good pasta sauce like the Sturdy Garlic & Herb Sauce we’re using here, you don’t have to spruce it up. Our high-protein pasta sauce is doing all the heavy lifting for you with bold garlic, fresh herbs, and a rich tomato base. 


What You’ll Need 

  • 2 jars (36 oz) Sturdy Garlic & Herb Sauce 
  • 1 lb ground beef or ground turkey for a lighter option
  • 1 box (16 oz) of spaghetti 
  • 1 lb mild Italian sausage
  • 1/4 white onion, diced
  • 1/4 bell pepper, diced
  • 2 green onions, chopped
  • 4 garlic cloves, minced
  • 8 oz sour cream
  • 5 oz cottage cheese
  • 4 oz room-temperature cream cheese
  • 1-2 green onions, chopped
  • 16 oz grated mozzarella cheese
  • Parmesan cheese
  • Salt & pepper 
  • Dried or fresh parsley


How to Make It 

  1. In a large pan over high heat, cook 1 lb ground beef, breaking it up into small pieces. Drain the fat.
  2. Lower the heat to medium, add 1 lb mild Italian sausage, and cook until it’s mostly done.
  3. Toss in the onion, bell pepper, and green onion. Cook until the onions are soft.
  4. Add 4 minced garlic cloves and cook for 1 more minute.
  5. Add 36 oz of Sturdy Garlic & Herb Sauce and stir everything together. Let it simmer on low for 30–45 minutes, stirring occasionally.
  6. Boil a pot of salted water and cook 16 oz of spaghetti until al dente. Drain and set aside.
  7. In a bowl, mix together 8 oz sour cream, 5 oz cottage cheese, 4 oz cream cheese (room temp), and the rest of your chopped green onion. Add salt and pepper to taste.
  8. Grab a 9x13" baking dish and spread a layer of meat sauce on the bottom. Sprinkle some Parmesan cheese on top.
  9. Layer everything.
    • Add all the spaghetti in a single layer.
    • Spread the cheese mixture evenly over the pasta.
    • Add the rest of the meat sauce.
    • Top with 16 oz shredded mozzarella and a sprinkle of dried parsley.
  10. Bake uncovered for 30–45 minutes, or until the top is golden and bubbly. Broil for 2–3 minutes at the end if you want extra browning.
  11. Add more chopped green onions or fresh parsley during the last 10–15 minutes of baking.
  12. Let it sit for 10–15 minutes before serving, or dig in while it’s hot and melty. Up to you.
