Easy Baked Penne Recipe

Years ago I had a friend who introduced me to this easy baked pasta recipe. She made it for a 4th of July barbecue one time and we sat eating it for hours. I’ve been making it for potlucks and family dinners ever since.

When I researched baked penne pasta recipes online before making it, I found that so many of them have meat in them. I thought that was strange, because I’ve only ever had THIS Baked Penne, which is vegetarian. My friend didn’t eat meat, so neither did her pasta recipe. As a result, I’ve always made this without meat. And you know what? I don’t miss the meat at all – plus I often serve it with a side of baked or grilled chicken or some meatballs for protein. After all, it makes a HUGE batch, so we’re often eating it at a potluck.

The recipe is easy, using just a handful of ingredients, and comes together in minutes. Plus, do you see how cheesy this baked penne is??? OMG.

Secret Ingredients

There are two secret ingredients in this baked penne pasta. Can you guess what they are? They’re two things I’d never seen in a pasta recipe before, but they make the end result so cheesy and creamy I just never leave them out.

By the way, these two ingredients, if they weird you out, are two things I never eat alone. I ONLY use them in recipes, like Cheesy Egg Casserole.

Sour Cream and Cottage Cheese. I KNOW! So weird in a baked pasta dish, right? BUT, hear me out.

The cottage cheese adds body (and protein) to the dish. You don’t taste it at all, plus it makes it even more cheesy. There’s TONS of mozzarella to make you forget about the cottage cheese, but this dish wouldn’t be as good without it.

Sour cream adds so much creaminess to this easy baked penne recipe. This result is almost like a creamy tomato sauce.

What other ingredients are there? Just pasta, pasta sauce, and garlic. You can use any jarred pasta sauce you like (I’ve used a variety of brands). OR, you can make your own red sauce. I love these recipes for easy homemade marinara sauce, this vodka sauce, and this spicy pomodoro sauce.

I always kick it up by adding TONS (5 cloves) of pressed garlic. If you’re not a garlic lover, you can leave that out, but it gives a wonderful flavor to the dish. (Plus, it wards off vampires.) Then you add tons of cheese and bake it up.

How to Make Easy Baked Penne

  1. Cook and drain the pasta. This is a great use for leftover pasta!
  2. Stir together the sauce, cheeses, and garlic.
  3. Stir in the pasta and place it in the pan. Add more cheese!
  4. Bake until bubbly and golden.

This dish is good from the oven, but I also eat it for days leftover, and I’ve even frozen leftovers. It feeds a lot of people so it’s perfect for a big family or a party. And you won’t miss the meat, although you can add some if you like (see note).

  1. I have made this several times now and must sat IT IS DELICIOUS! Perfect for a damp, chilly day (like today). Very quick to make and can taste different depending on what sauce you use. Love it!

  2. Did everything exactly but added diced red onions, green, yellow, and red peppers, along with mushrooms to make it more vegetarian divine and everyone loved it. I added some oregano, basil, and lemon pepper to the mixture with 6 cloves of garlic (cause I love garlic) and this was marvelous. Thank you Dorothy for your recipes.

  3. I’m going to make this. Actually, I grew up eating my grandmother’s egg noodle casserole made with sour cream, cottage cheese, butter and broad noodles… topped with Rice Krispies! Sounds bad but tastes delicious 😋

  4. I made this tonight and my family devoured it. At first, I didn’t think it would be enough but I was pleasantly surprised not only how much it made but how filling and delicious it was. Thank you for posting this quick and easy tasty meal!

  5. Dorothy, this looks so good! I’m all about the cheese and dairy! Do you happen to know where your friend got her original recipe?

  6. I tripled this recipe to serve at my son’s swim team dinner. It turned out so good! All the kids want it served at the next dinner. The sour cream and cottage cheese were perfect!

  7. I made the East baked penne. turned out amazing. I do admit I had reservations about cottage cheese and sour cream. it’s all gone. delicious

  8. Made this tonight and it was so so good! I did add some sautéed chicken and mushrooms just because I like to add that to pasta dishes. But I could totally see not adding it and it being just as amazing! Thank you for the recipe, will be making again!
