What.a.week. Government shutdown, eh? How about them apples?! All I have to say is, HA! and WHAT???

That’s all. I’m not pointing fingers at anyone…

Anywho. Ever feel like you overdo it? I did something that I should never do when I feel a bit stressed out… 

I went to Target. Retail therapy called and she said Target was the place to be…so I listened. I came home with new jeans, new shirts, new dress, new shoes… Looks like my husband will renew me when that Amex bill gets here. 😀

So, that’s one way of overdoing it. Another way of overdoing it is by making everything Loaded Baked Potatoes.

Look in the archives – you’ll see what I mean. We have Loaded Baked Potato Rounds, Loaded Baked Potato Bites, and here we are today, about to share a Loaded Baked Potato Casserole. Are you going to complain? Don’t. This is really good stuff. Like, reaaaalllllyyyy.

For someone who almost exclusively wants to eat chicken salads and chocolate, I am kinda surprised at myself for making all these potaytah dishes. It might have something to do with buttering-up the hubs, Goce. I’m subconsciously trying to make it all-good before that bill gets here. There’s also a new living room set on that same credit card… Joss & Main pulled me in – I couldn’t say NO!

By the ways, neither Target nor Joss & Main even know me – this is not sponsored by them – I’m just sharing my addictions. Which are not so bad… In fact, I love ’em!

I can’t even describe how excited I was when the bedroom set arrived from there! Oh my gosh… my husband thought we won the lottery! Let’s not get into that because this post will be all about linens, drapes, tufted furniture, and rustic floors!

Okay…potatoes. Loaded. With bacon and cheese. MAKE IT! Serve it! LOVE IT!

      Hi Abby!

      You can definitely half it, but I’m not completely sure on the cooking-time. I would suggest to start checking at about the 45-minute mark. You can insert a toothpick in the center of the casserole, and if it comes out clean, it’s done, if it’s wet, give it a few more minutes. I hope this helps. Let me know how it goes!

  1. Made this for dinner tonight it was really good. I just needed to cook it a little longer. I also switched it up a bit I added sour cream in the middle layer and instead of putting the bacon on the inside I waited until it was cooked and added cheese in top and sprinkled the bacon.

  2. This could do with AT LEAST 20 minutes less bake time. The potatoes were absolute mush with your 75-90 + 10-15 uncovered cooking instructions. Could also do with some cheese or bread crumbs on top.

      Hi Jared! I’m really sorry that it didn’t turn out for you. I have made this in two different ovens – at my mom’s, it bakes in exactly 90 minutes + 10 more, uncovered. In my oven it bakes at just over 75 minutes and it also needs close to 10 minutes, uncovered. SO, maybe you have a super-oven?? I need to get me one of those! 😀

        I’m thinking Jared sliced the potatoes to thin that’s why they came out the way they did!

    1. Answered my own questions by attempting. To anyone who sees this, yes, cover the dish, or it’ll cook in under half the time, but the top will be dried out, and the temperature given is in F. Use 190 if you’re using C.

        Hi Zero! My apologies, please. I did not see your question. Very often some comments go into a “spam” folder and I don’t see them.
        But, as you already figured it out, 🙂 yes, cover the dish and the temp is listed in fahrenheit. Have a great day!

  3. Thank you, thank you, thank you for this recipe! I made it this weekend and it was a HUGE hit! I used tex mex and mozzarella for the cheese because that’s what I had on hand, and it turned out amazingly. My boyfriend told me the morning after we had it for dinner that he had dreamed about it that night. Oh boy. Looks like it will be on the menu again soon!!

      Hi Val! I want to say yes, but because I haven’t tried it, I’m not sure… however, that certainly sounds delicious!! Great idea!

  4. I wanted to try this recipe soooo bad! It looked amazing, and I was right. The only problem however is that it took twice as long to cook! The hubby was starving once 7;30 rolled around and I was out of excuses as to why I kept feeding him sliced bread… Other than that it was very good, specially with the extra amount of bacon added in.

      3 hours to cook it?! OH NO! I’m SOOOO sorry it took that long… your poor hubby! At least he waited. 🙂 I wonder what could have caused that? Or is my oven a rock star and bakes things in half the time?! 😉
