Twice Baked Potatoes Casserole Recipe: Loaded With Cheese and Bacon

This casserole transforms classic twice-baked potatoes into a crowd-friendly dish with all the same loaded appeal. The method streamlines individual potatoes into one pan while keeping every bite packed with flavor.

I developed this approach for holiday gatherings where oven space is limited. The potatoes bake until tender, then get scooped, mixed with cheese and bacon, and returned to the oven for a golden finish.

What emerges is a creamy, cheesy casserole with crispy edges and that familiar twice-baked texture. The bacon adds smoky depth while the cheese creates a rich, velvety sauce that binds everything together.

It serves a group effortlessly and always disappears first. The preparation is straightforward, with most of the work happening in the oven.

Ingredients for Twice Baked Potatoes Casserole

Russet potatoes, sharp cheddar, and smoky vegetarian bacon create this crowd-pleasing casserole with twice-baked texture.

The potatoes are the foundation—Russets give the right fluffy texture. Look for firm, unblemished spuds at Whole Foods or your local market. The cheddar should be block cheese you grate yourself; pre-shredded has anti-caking agents that make the sauce grainy. For the vegetarian bacon, MorningStar or Lightlife brands work well, but crumbled tempeh adds great texture too.

No vegetarian bacon? Smoked tofu or mushrooms add that meaty depth. Half-and-half can stand in for whole milk if you want extra creaminess. Fresh chives instead of dried? Use three times as much. The Dijon is worth including—it brightens the richness. If you’re avoiding dairy, vegan cheese shreds and coconut milk make excellent substitutes.

Assemble the casserole up to a day ahead—just wait to add the topping until baking. Leftovers keep 4-5 days in the fridge and reheat beautifully. For make-ahead, freeze unbaked casserole for up to 3 months (thaw before baking).

Step-by-Step Instructions for Twice Baked Potatoes Casserole

Master this technique for a crowd-pleasing dish with crispy edges and creamy centers.

Step 1: Prepare and Bake the Russet Potatoes

Preheat your oven to 400°F. Scrub the 4 lb Russet Potatoes clean and pierce each all over with a fork. This prevents steam buildup during baking that could cause them to burst.

Place the potatoes directly on the oven rack and bake for 45-60 minutes until tender when pierced with a knife. You want them soft enough to easily scoop out the flesh but firm enough to hold their shape when halved. Remove and let cool slightly—about 10 minutes—so they’re safe to handle.

Step 2: Scoop and Mash the Potato Flesh

Cut the baked potatoes in half lengthwise and carefully scoop out the flesh, leaving a ¼-inch-thick shell to maintain structure. Place the scooped flesh in a large mixing bowl.

Add the 0.5 cup Unsalted Butter, 1 cup Whole Milk, 1 cup Sour Cream, 3 cloves minced Garlic Cloves, 1 tbsp Dijon Mustard, 1.5 tsp Kosher Salt, 1 tsp Black Pepper, and 1 tsp Paprika to the bowl. Mash until smooth with a few lumps for texture. The mixture should be creamy but not runny—if too thick, add a splash more milk.

Step 3: Fold in Cheese and Bacon

Gently fold 2 cups of the Sharp Cheddar Cheese and the 1 cup Vegetarian Bacon Bits into the mashed potato mixture. Reserve the remaining 1 cup Sharp Cheddar Cheese for topping. This step ensures even distribution of flavor in every bite.

Spoon the mixture back into the hollowed-out potato shells, mounding it slightly at the top. Arrange the filled halves in a baking dish, leaving a little space between each for even browning.

Step 4: Bake Until Golden and Bubbly

Sprinkle the reserved 1 cup Sharp Cheddar Cheese evenly over the tops, then dust with the 1 tbsp Dried Chives for a subtle onion note. Bake at 375°F for 20-25 minutes until the tops are golden brown and the cheese is fully melted and bubbling.

If the tops aren’t browning enough, broil for 1-2 minutes at the end, watching closely to avoid burning. The casserole is ready when the edges are crisp and the centers are heated through.

Step 5: Garnish and Serve

Remove from the oven and let rest for 5 minutes to set slightly. Garnish with the 0.5 cup Green Onions for a fresh, crisp contrast to the rich, creamy filling.

Serve warm, ensuring each portion includes a mix of the crispy cheese topping and the velvety potato base. The flavors deepen as it sits, so leftovers reheat beautifully at 350°F for 15-20 minutes.

Best Sauces and Condiments for This Recipe

Classic Cheese Sauce

A velvety cheddar cheese sauce takes this dish over the top. Melt 2 tbsp butter in a saucepan, whisk in 2 tbsp flour, then slowly add 1 cup whole milk and 1 cup shredded sharp cheddar. Stir until smooth and creamy. 🧀

Creamy Garlic Aioli

Blend ½ cup mayonnaise, 2 minced garlic cloves, 1 tbsp lemon juice, and 1 tsp Dijon mustard for a tangy dip. I love how the garlic cuts through the richness of the potatoes.

Spicy Chipotle Crema

Mix ½ cup sour cream with 1 tbsp adobo sauce from canned chipotles and ½ tsp lime zest. This adds a smoky heat that pairs perfectly with the bacon and cheese. 🌶️

Fresh Herb Garnish

Combine ¼ cup chopped parsley and 2 tbsp chopped chives with 1 tbsp olive oil. Sprinkle this fresh herb mix over the casserole right before serving for a pop of color and freshness.

Smoky BBQ Drizzle

Warm ¼ cup BBQ sauce with 1 tsp smoked paprika for a sweet and smoky drizzle. I use Stubb’s Original for its balanced flavor profile.

Crunchy Topping

Toast ½ cup panko breadcrumbs with 1 tbsp melted butter and ¼ tsp garlic powder until golden. Sprinkle this over the casserole during the last 5 minutes of baking for added texture.
