It’s January 1, and I always love the promise the new year brings of better things to come.  And this January is bringing a better way to find recipes by diet type on Kalyn’s Kitchen, so I’m excited about that.  Happy New Year to all my readers and friends!

 

Although I usually start each month with the round-up of Deliciously Healthy Low-Carb Recipes from the previous month, I wanted to start the new year with a brand new recipe.  This Low-Carb Mock Lasagna Spaghetti Squash Casserole is something that really knocked our socks off when we tested the recipe, and if you’re in the need of some low-carb comfort food, I promise this will hit the spot.

For the month of January I’ll be focusing on Low-Carb Recipes like I do every year on the blog, so I’ll be back soon with that round-up of all the Deliciously Healthy Low-Carb Recipes I posted or spotted during December.

I roasted two spaghetti squashes for this, but in the end I realized if you have one large one (about 4 pounds), it will be plenty for the casserole.  Microwave the squash about 5 minutes to soften, cut the spaghetti squash in half, scrape out seeds, rub with olive oil and Italian herb blend, and roast 50-60 minutes.  (If you want an easier method, you can cook the spaghetti squash in a crockpot  or cook the spaghetti squash in a pressure cooker for this recipe.)

While the squash cooks, squeeze the turkey sausage out of the casings and brown well.  Add the marinara sauce (bottled or homemade is fine), dried basil, Italian herb blend, and garlic powder and simmer until the liquid is mostly evaporated, about 30 minutes.  Mix together the cottage cheese, eggs, and Italian Herb blend.

Top with another layer of spaghetti squash, sauce, cottage cheese mixture, and the rest of the cheese.  Bake uncovered at 375F/190C for about 45 minutes.  (Mine got a little brown on the edges, but that didn’t bother us a bit.)  Serve hot and devour!

 

Low-Carb Mock Lasagna Spaghetti Squash Casserole

(Makes 6 – 8 servings, depending on what you serve it with; recipe created by Kalyn.)

Spaghetti Squash Ingredients:
1 large spaghetti squash, about 4 pounds
2 tsp. olive oil (for brushing squash)
2 tsp. Italian Herb Blend (for sprinkling on squash before roasting)

Sauce Ingredients:
2 tsp. olive oil
5 links (19.5 oz.) hot turkey Italian Sausage
3 cups marinara sauce (Use a 24 oz. jar or homemade marinara sauce; look for the sauce with the least sugar if you use sauce from a jar.)
1 tsp. dried basil
1 tsp. Italian Herb Blend
1 tsp. garlic powder (or use minced fresh garlic if you prefer)

Casserole Ingredients:
2 cups cottage cheese (regular or low-fat)
2 eggs
1 tsp. Italian Herb Blend
2 cups grated Mozzarella (regular or low-fat)
1/2 cup coarsely grated Parmesan cheese (plus more to add at the table if desired.)

Instructions:

Preheat oven to 400F/200C.  If desired, microwave the spaghetti squash for about 5 minutes (to soften the skin so it’s easier to cut.)  Cut squash in half lengthwise and scrape out the seeds.  Brush the inside of each half with olive oil and sprinkle with Italian Herb Blend.  Roast the squash on a flat baking sheet about 50-60 minutes, or until the squash strings apart easily with a fork.  (You can also  cook the spaghetti squash in a crockpot or cook the spaghetti squash in a pressure cooker for this recipe.)

 

While the squash cooks,  heat the olive oil in a large non-stick frying pan, squeeze the turkey sausage out of the casings, and brown sausage well, breaking it apart with a turner while it cooks. (I like to use an old-fashioned Potato Masher to break the sausage apart.)  When the sausage is well-browned, add the 3 cups of sauce, dried basil, Italian Herb Blend, and garlic powder, and simmer on low until most of the liquid has evaporated, about 30 minutes.Put the cottage cheese into a bowl, add the eggs and Italian Herb Blend, and mix with a fork until the egg is well-mixed into the cottage cheese.  Prepare grated Mozzarella and coarsely grated Parmesan.  Spray an 8 inch by 11 inch casserole dish with non-stick spray.  (You can also use my favorite square glass casserole dish, but for this recipe I liked the rectangular dish a little better.)

When the spaghetti squash is done, turn oven heat down to 375F/190C and let squash cool for a few minutes.  Then use a fork to scrape the squash away from the skin, separating it into strands of “spaghetti.”  Discard the skin.

In the casserole dish, layer half the spaghetti squash, half the reduced sauce mixture, half the cottage cheese mixture, half the Mozzarella, and half the Parmesan.  Repeat with another layer each of squash, sauce, cottage cheese mixture, Mozzarella, and Parmesan.

Bake uncovered until the casserole is bubbling hot and the cheese is melted and lightly browned, about 40-45 minutes.  Serve hot, with additional Parmesan cheese to add at the table if desired.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:

If you’re making this for the South Beach Diet, they would recommend using low-fat cottage cheese and low-fat Mozzarella (as well as low-fat turkey Italian sausage.)  For other types of low-carb diets, use full-fat cheese if you prefer, but I would still prefer the less fatty turkey sausage for this recipe.  Spaghetti squash only has about 7 carbs in one cup, making this recipe a good choice for any type of carb-conscious eating plan.

  1. Spaghetti squash is very high on my list for January (as you'll see in my posts later this month). For speed, I cook it in the pressure cooker, but oven roasting brings out more of the natural sweetness.

  2. This is making me hungry! Can I find this squash this time of year??? If so, this will be on my table this weekend!

  3. We are looking for healthy choices that hold up well to freezing individual portions for work lunches. Do you know if this delicious-sounding recipe will freeze well?

    • Yes, I definitely think this will freeze well. By the way, you can look for the tag "Can Freeze" at the end of posts to see which things I think will freeze well or see thumbnails of all those freezer-friendly recipes on the page for Can Freeze. Hope that is helpful for you; I'm excited about this new feature!

  4. I made this last night and it was delicious! My only problem was it was a little watery, I am thinking that maybe it was the cottage cheese.

  5. Made this tonight and it was wonderful! I went the lazy route and microwaved the squash for 12 minutes instead of roasting and it turned out fine. Thanks for the creation 🙂

  6. I loved this recipe! Trying to be healthy to lose some weight and pasta is a vice… so I've now fallen in love with spaghetti squash. This recipe is just like lasagna… even better the following days!

  7. THIS WAS AMAZING AND SO STINKING SIMPLE!!!! Thank you so much.

  8. Wonder what I could sub for the cottage cheese, cannot do sheep or cow dairy. I will use buffalo mozzarella for the cheese part. This sounds delightful.

  9. What temp do you bake the lasagna once assembled? 375 or 400?

  10. I made this for lunch today and it's amazing. I tweaked it by using low fat cottage cheese and part-skim milk. Then veggie crumbles instead of meat along with a ton of spinach tossed into the cottage cheese mixture. This is wonderful. I think it will be even better twice baked! Thanks so much!

  11. I would love to try this but my son is allergic to eggs. Do you have any suggestion for egg substitute?

    • Really the only purpose of the egg is to help the casserole hold together better. I'd just make it without the egg, knowing you'll have to take the pieces out a bit more carefully when you serve it. I think it will still taste great. Hope you enjoy!

  12. This was absolutely delectable. Both the Husband and I declared the recipe a keeper. The left-overs were just as good, if not better than the first sitting. I must confess, I did sub ricotta for the cottage cheese, as it is more traditional for me than cottage cheese (and I don’t like cottage cheese at all!) in lasagna. Thanks for another great recipe!!!

  13. Thanks for the delicious recipe my first time having spaghetti squash and I’m hooked

  14. Making it right now with ricotta cheese. I think I will squeeze the squash with paper towel to get out water.
