Ingredients for Bisquick Impossible Pie

Pantry staples plus a few fridge favorites—this impossible pie comes together faster than breakfast cereal.

The Bisquick is non-negotiable here—it’s what creates that magical self-forming crust. I always grab the original version (not Heart Smart or gluten-free) for best results. The milk matters too: whole milk gives you the richest custard texture, but 2% works in a pinch. For the ham, deli counter thick-cut is ideal, but those pre-diced packages save time. Just make sure it’s fully cooked before adding to the batter (no one wants rubbery ham).

No ham? Cooked bacon, crumbled sausage, or even diced bell peppers work great. Cheese swaps are endless—Pepper Jack for heat, Swiss for nutty flavor. Out of green onions? Chives or regular yellow onions (sautéed first) do the trick. The dried mustard is optional but adds depth—Dijon mustard at half the amount if that’s what you’ve got. And if you’re making this dairy-free, unsweetened almond milk and vegan cheese work, though the texture changes slightly.

This pie keeps 3-4 days in the fridge—reheat slices in the microwave (30 seconds) or toaster oven for crispy edges. Freeze extras (up to 2 months) wrapped tight in foil. The batter can be mixed the night before too—just store it covered in the fridge and bake in the morning. Leftovers make killer breakfast sandwiches with an English muffin.

Step-by-Step Instructions for Bisquick Impossible Pie

Here’s how to make this breakfast magic happen—fast, easy, and foolproof.

Step 1: Prep the Ingredients and Oven

First things first, preheat your oven to 350°F. This gives you time to get everything ready while the oven comes up to temperature. Melt the 2 tablespoons unsalted butter and let it cool slightly—you don’t want it hot when you mix it in.

In a large bowl, whisk together the 1.5 cups whole milk, 4 whole large eggs, 0.25 teaspoon salt, 0.25 teaspoon ground black pepper, and 0.5 teaspoon dried mustard powder. I like to crack the eggs into a separate small bowl first—just in case any shells decide to jump in. Whisk until everything is fully combined and you see no streaks of egg white.

Step 2: Combine Wet and Dry Ingredients

Now add the 1 cup Bisquick Original Baking Mix to your wet ingredients. Gently whisk just until the dry mix disappears—don’t overdo it. A few small lumps are fine; overmixing makes the pie tough instead of fluffy. Pour in the melted butter and whisk for another 10-15 seconds until just incorporated.

Here’s where the magic starts: stir in the 1 cup shredded cheddar cheese, 1 cup diced cooked ham, and 0.25 cup diced green onions. The batter will look thick with all these goodies suspended in it—that’s exactly what you want. Let it sit for 2 minutes while you prep your baking dish.

Step 3: Bake Until Golden and Puffy

Pour the batter into a greased 9-inch pie plate or similar-sized baking dish. The mixture will look shallow in the dish, but trust me—it puffs up beautifully. Bake at 350°F for 30-35 minutes until the top is golden brown and the center is set.

You’ll know it’s done when a knife inserted in the center comes out clean and the edges have pulled away slightly from the sides of the dish. Don’t open the oven before 30 minutes—that sudden temperature change can cause the pie to fall. The top should have a nice crust while the inside stays custardy and tender.

Step 4: Rest Briefly and Serve Warm

Let the pie rest for 5 minutes after removing it from the oven. This short wait allows the structure to set so it slices cleanly. You’ll see it deflate slightly—that’s normal and actually helps create that perfect texture contrast between the crispy top and creamy interior.

Slice into wedges and serve immediately while warm. Each bite should give you that perfect combination of fluffy egg custard, melty cheese, savory ham, and just a hint of onion sharpness. This pie is fantastic on its own, but a dollop of sour cream or hot sauce takes it over the top if you’re feeling fancy.

Dietary Considerations for bisquick impossible pie

Gluten-Free Adaptation

For a gluten-free version, swap the Bisquick Original for Bisquick Gluten-Free Baking Mix. I’ve tested this substitution multiple times, and the texture comes remarkably close to the original. Just be sure to check that all other ingredients (like your ham and cheese) are certified gluten-free, as some processed foods contain hidden gluten. 💡

Dairy-Free Modifications

To make this dairy-free, use unsweetened almond milk or oat milk instead of whole milk. For the cheese, Daiya Cheddar Shreds melt beautifully in this recipe. Replace the butter with 2 tablespoons coconut oil (melted and cooled). The flavor profile changes slightly but remains delicious.

Vegetarian Option

Skip the ham entirely and add 1 cup sautéed mushrooms or diced bell peppers instead. For extra protein, stir in ½ cup crumbled feta or diced tofu that’s been pan-fried until golden. The green onions still add that fresh pop, but you could also sprinkle sun-dried tomatoes on top before baking.

Lower-Carb Approach

While not truly keto, you can reduce carbs by using ½ cup almond flour plus ½ cup Bisquick instead of the full cup. This changes the texture slightly, making it denser but still satisfying. Pair it with sugar-free bacon and extra cheese to balance the macros. The crust won’t puff quite as dramatically, but the flavor remains rich.

Egg Substitutes

For those avoiding eggs, use 1 cup silken tofu (blended smooth) plus 1 tablespoon cornstarch to replace the 4 eggs. The texture becomes more custard-like and less fluffy, but still holds together well. I’d recommend adding an extra ¼ teaspoon baking powder to help with rise. Bake for an additional 5-7 minutes to ensure it sets properly.

Sodium Reduction

To cut back on sodium, use low-sodium ham and reduced-sodium cheddar cheese. Omit the added salt entirely—the Bisquick and cheese provide enough saltiness. Boost flavor with extra black pepper, smoked paprika, or fresh herbs like dill or parsley. The green onions add brightness without extra sodium too. 🌱
