Quick and Easy Keto Dinner Recipe

To make this keto casserole recipe even easier, I cook the spaghetti squash the night before. That way I simply brown the meat, toss the ingredients in a bowl, and throw it in the oven for a wonderful grain-free dinner.

  1. Hi Elana, I made this and we thought it was awesome. I also love how easy it is to prepare. Would you answer a question for me, though? How does your family eat this? Just on a plate with a fork? Do you put anything on top? I had a chopped tomato on top of my leftovers and it was yummy. Sorry if these are odd questions.

    • Heather, no need to apologize, I think those are great questions! We slice it and transfer it to a plate and eat with a fork :-)

  2. Elana,

    I’m scouring the supermarkets and health food stores and I’m finding more and more products made with almonds, grain free, and made with veggies. I’ve found pasta made with mostly chickpeas, black beans, and edamame, from a company called Explore Cuisine. The products have a little rice or tapioca flour.

  3. Hi Elana,
    I have your three cook books and love them. I’m thinking of trying Keto and was wondering which Keto books you would recommend.
    Thanking you in advance,

  4. Oh wow! This recipe looks totally amazing and I love, love, love the new format for your website. You’ve come a long way, Baby…
    Thank you so much. When I make this I shall return to leave a review. Take care, Elana

  5. Cooking squash now to make this later today. Cannot wait! I have ‘love loved’ so many of Elana’s recipes over the years – my goto healthy food blog! And this new look on the interface is fantastic! Thanks for all you do!

    • Daphne, thanks for your wonderful comment! I’m so glad you are enjoying my site and that it is your goto healthy food blog :-)

  6. It looks delicious! There will be a time down the road that I will make this. I have enjoyed many of Eleana’s recipes over the year’s. I’ve even “tweaked” several Paleo recipes into allowable Keto recipes. With that said, spagetti squash is a higher carb veggie and not recommended for the Keto lifestyle if you are trying to lose weight or have major health issues. It is recommended, though, for carb-up days or maintenance. Thank you for all the time you spend in helping us all to make wise health choices and sharing your health journey with us ❤️

    • Ellen, thanks so much for your comment! The spaghetti squash in this recipe contains 4g carbs per serving, a very reasonable amount for someone following a strict Keto Diet and looking to keep carbs under 20 grams per day :-)

  7. I will try this Paleo and report back. Will probably use heavy coconut cream, nondairy mozzarella cheese and nondairy Parmesan cheese. My system doesn’t deal with dairy very well. Especially heavy cream.
