Ingredients for betty crocker cream of mushroom soup
Betty Crocker cream of mushroom soup meets creamy casserole perfection with these 13 pantry staples.
| Ingredient | Amount | Notes |
|---|---|---|
| Betty Crocker Cream of Mushroom Soup 🍲 | 2 cans | Condensed, 10.5 oz each |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, aged preferred |
| All-Purpose Flour 🌾 | ½ cup | For thickening |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed |
| Panko Breadcrumbs 🍞 | 1 ½ cups | For crispy topping |
| Freshly Grated Parmesan Cheese 🧀 | ¼ cup | From aged block |
| Medium Russet Potatoes 🥔 | 2 whole | Peeled, thinly sliced |
| Yellow Onion 🧅 | 1 whole | Diced, medium size |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
The Betty Crocker soup is the foundation—condensed cans save time without sacrificing flavor. For the cheeses, sharp cheddar melts beautifully while aged Parmesan adds umami depth. I recommend Kraft Natural for cheddar and Parmigiano-Reggiano for Parmesan to avoid the chalky texture of pre-grated. The Russet potatoes should be firm and starchy—Idaho potatoes are ideal. If you're short on time, pre-sliced frozen potatoes work in a pinch. For the onion, yellow has the best balance of sweetness and sharpness, while red adds subtle color without altering flavor.
No heavy cream? Half-and-half or whole milk can substitute, though the texture will be slightly lighter. Sharp cheddar can be swapped for Gruyère or Monterey Jack for a different flavor profile. Panko breadcrumbs are non-negotiable for texture—regular breadcrumbs get soggy. Need to skip the Parmesan? Nutritional yeast adds a cheesy note without dairy. The garlic can be jarred minced if fresh isn't available, but fresh is worth the extra minute. For the thyme, fresh leaves are best, but dried works at one-third the amount. The soup can should be unopened for this recipe—opening it first makes the filling too runny.
This casserole reheats beautifully—5 minutes at 350°F brings it back to creamy perfection. Store leftovers in an airtight container for up to 5 days in the fridge. For longer storage, portion into freezer-safe containers and freeze for up to 3 months. The breadcrumb topping can be prepped ahead and stored in the fridge for 2 days, or frozen for 1 month. For extra crispiness, broil for 2-3 minutes before serving. The flavor actually improves after 24 hours in the fridge as the ingredients meld together.

Step-by-step instructions for creamy mushroom potato bake
Transform simple ingredients into a restaurant-worthy dish with this elevated Betty Crocker-inspired method.
Sauté the Aromatic Base
Heat a large skillet over medium heat and melt the 0.5 cup unsalted butter until it foams. Add the 1 whole yellow onion and 3 cloves garlic cloves, cooking for 5-6 minutes until the onion softens and becomes translucent. This foundational step develops depth of flavor that carries through the entire dish.
Season immediately with 1 tsp kosher salt, 0.5 tsp dried thyme, and 0.5 tsp ground black pepper. Stir frequently to prevent burning—garlic should smell fragrant but not brown. The butter will release its nutty aroma, creating the perfect canvas for the creamy sauce to come.
Build the Creamy Sauce Foundation
Increase heat to medium-high and sprinkle the 0.5 cup all-purpose flour over the onion mixture. Stir vigorously for 1-2 minutes until the flour turns golden brown and the mixture thickens—this creates a roux that will form the backbone of your sauce. Immediately pour in 2 cans Betty Crocker Cream of Mushroom Soup and stir until completely combined.
Reduce heat to medium-low and let the mixture simmer for 3-4 minutes, stirring occasionally. The sauce should begin to thicken noticeably. This step is where the magic happens—the mushroom flavor intensifies while the roux develops its signature richness. If the sauce thickens too quickly, add 2 tablespoons water to maintain proper consistency.
Incorporate Cream and Cheese
Pour in the 0.5 cup heavy cream and stir until smooth. The sauce should immediately become velvety and luxurious. Gradually add the 1.5 cups sharp cheddar cheese, stirring constantly until fully melted and incorporated. The cheese should create a glossy, creamy texture that coats the back of a spoon.
Taste and adjust seasoning—you may need an additional pinch of salt or pepper to balance the flavors. This is your final opportunity to refine the sauce before it's combined with the potatoes. The mixture should be thick enough to coat a spoon but still flow smoothly when poured.
Prepare and Layer the Potatoes
While the sauce simmers, peel and thinly slice the 2 whole medium russet potatoes into ¼-inch thick rounds. You should have about 4 cups of sliced potatoes. Arrange half of the potato slices in an even layer in a 9x13-inch baking dish, slightly overlapping them. Pour half of the creamy sauce mixture over the potatoes.
Repeat with the remaining potato slices and sauce, creating a second layer. The potatoes should be mostly submerged in the sauce but visible at the top. Sprinkle the 0.25 cup freshly grated parmesan cheese evenly over the top layer, creating a beautiful golden crust when baked.
Create the Crispy Breadcrumb Topping
In a small bowl, combine the 1.5 cups panko breadcrumbs with 0.5 cup unsalted butter, melted and cooled slightly. Mix until the breadcrumbs are evenly coated and appear slightly moistened. This creates a crispy, buttery topping that will contrast beautifully with the creamy filling.
Sprinkle the buttered breadcrumb mixture evenly over the entire surface of the potato bake. Press down gently to help it adhere to the top layer. Bake uncovered at 375°F for 30-35 minutes until the top is deep golden brown and the edges bubble around the sides. The potatoes should be tender when pierced with a fork, and the sauce should be thick and creamy.
Pro Tips For Making Betty Crocker Cream Of Mushroom Soup
- Temper the Cheese: Grate that sharp cheddar yourself instead of buying pre-shredded—it melts smoother and doesn’t clump like store-bought bags. If you’re in a rush, toss the grated cheese with 1 teaspoon of flour first to help it blend better into the soup.
- Simmer, Don’t Boil: The moment you add the heavy cream, drop the heat to medium-low and stir constantly. I learned this the hard way—boiling the cream turns it grainy and ruins the creamy texture you’re working for.
- Toast the Flour First: Melt the butter in a saucepan, then whisk in the flour and cook it for 1-2 minutes until it’s golden and smells nutty. This step makes the sauce richer and cuts down on that raw flour taste—trust me, it’s worth the extra 60 seconds.
- Strain for Smoothness: If your soup ends up lumpy, don’t just stir it out—strain it through a fine-mesh sieve into a clean pot. It’s a little extra work, but the result is silky, restaurant-quality consistency every time. (Yes, even if you’re impatient like me.)
Troubleshooting great betty crocker cream of mushroom soup
Sauce Too Thin?
If your sauce separates or looks too thin after mixing, the issue is likely undercooked roux or excess liquid. Simmer the sauce uncovered for an extra 5 minutes to evaporate moisture, stirring constantly.
For immediate thickening, mix 1 tablespoon cornstarch with 1 tablespoon cold water, then whisk into the sauce until it reaches a velvety consistency. I've found that using Betty Crocker cream of mushroom soup directly from the can (not warmed) helps maintain proper thickness. 🌡️
Potatoes Staying Crunchy?
Undercooked potatoes are usually caused by insufficient baking time or overcrowding. Ensure your 9x13-inch baking dish has at least ¼-inch space between potato slices for even heat circulation. If using pre-sliced frozen potatoes, parboil them for 3 minutes before layering to jumpstart cooking.
For extra insurance, bake at 375°F for 40 minutes total—the internal temperature should reach 205°F for perfect tenderness.
Topping Not Crispy?
The breadcrumb topping needs proper moisture balance and heat exposure. Make sure your panko breadcrumbs are evenly coated with melted butter (not drowned in it)—they should hold together when pressed but not be soggy.
Press the topping firmly onto the casserole before baking, then broil for the final 2-3 minutes to achieve that coveted golden crunch. I recommend using a light-colored baking dish to prevent overheating at the bottom.
Cheese Not Melting?
Uneven heat distribution or cold cheese are the usual culprits. Stir the cheese into the sauce while it's still simmering (not boiling) to ensure even melting. For stubborn clumps, use sharp cheddar and grate it yourself—pre-shredded cheese contains anti-caking agents that prevent proper melting.
If needed, cover the casserole with foil for the first 15 minutes of baking, then remove to crisp the topping. 🧀
Sauce Too Salty?
Over-salting often happens when using pre-shredded cheese or canned soup. Taste your sauce before baking and adjust with splash of heavy cream (which dilutes salt) or a pinch of sugar (which balances flavors).
For future batches, reduce the salt in the soup by ½ teaspoon—the cheddar already contains significant sodium. I've also found that adding 1 extra garlic clove helps mask any lingering saltiness with fresh, aromatic notes.
Dish Too Dry?
Dryness typically results from over-baking or insufficient sauce. Check doneness at 25 minutes—the potatoes should be tender when pierced. If the sauce looks thickened but the potatoes are dry, add ¼ cup warm water or broth to the baking dish before the final 5 minutes of cooking.
For extra moisture, stir in 2 tablespoons sour cream along with the cheese during assembly. The key is maintaining a 1:1 ratio of sauce to potatoes in your layers.

Frequently asked questions
Can I substitute heavy cream with something lighter?
Yes! For a lighter version, replace the 0.5 cup heavy cream with 0.5 cup whole milk or half-and-half. The sauce will still be creamy but slightly less rich. For extra depth, add 1 tablespoon sour cream to maintain a velvety texture. The dish will be lighter but still delicious.
Can I make this recipe vegetarian?
This recipe is already vegetarian-friendly as is. For extra richness, use vegetarian cheddar cheese and ensure your Betty Crocker cream of mushroom soup is labeled vegetarian. The creamy sauce and crispy topping work perfectly for plant-based diets without any modifications.
How can I make this dish ahead of time?
Prepare the entire casserole up to the baking step and refrigerate it uncovered for up to 24 hours. When ready to bake, add 10-15 extra minutes to the 375°F baking time to account for the cold start. For freezing, assemble the dish, bake as directed, then cool completely. Store in an airtight container for up to 3 months. Reheat covered at 350°F for 20-25 minutes.
Can I use a different type of potato?
While russet potatoes are ideal for their fluffy texture, you can substitute with Yukon Gold or red potatoes. For best results, slice them ¼-inch thick and parboil for 2-3 minutes before layering. Avoid waxy potatoes like red potatoes if you prefer a creamier texture—they hold their shape better but can make the dish slightly denser.
Why does my topping get soggy?
Soggy topping usually happens when the breadcrumbs absorb too much moisture. Ensure your panko breadcrumbs are mixed with just enough melted butter to coat them lightly—think "damp sand" texture. Press the topping firmly onto the casserole before baking, and broil for the final 2-3 minutes to crisp it up. Using a light-colored baking dish also helps prevent overheating at the bottom.
