Essentials You'll Need

  • Crispy onions: These give the perfect crunch to every bite. You can buy them in a can or fry up your own.
  • Green beans: Use frozen French-cut if you want quick prep. Fresh beans taste great but need extra steps.
  • Cream cheese: This is how you make things extra smooth and creamy.
  • Garlic powder: Sprinkle in for bigger flavor, or leave it out if you don't feel like it.
  • Milk: Whole milk makes it super creamy—2% does the job too.
  • Broth: Chicken or veggie, your choice.
  • Flour: Toss in regular white flour to thicken everything up.
  • Butter: Go for salted if you have it; it'll add some depth.
  • Black pepper: Whether you use pre-ground or grind it fresh, you'll get a mild kick.
  • Salt: Just basic table salt, adjust as you go for taste.
  • Olive oil: Use any oil you like to get the mushrooms started.
  • Garlic: Fresh and finely chopped is best, or substitute with powder if needed.
  • Mushrooms: White or brown work awesome—chop them up. Even canned mushrooms are fine in a pinch.

Quick Steps to Get It Done

Start baking:
Fire up your oven to 350°F.
Chop your mushrooms and garlic:
Get everything diced nice and small.
Sauté it all:
Splash oil in a large pan. Cook the mushrooms, sprinkle salt and pepper, and let them get tender. Add that garlic last and let it get fragrant.
Build the sauce base:
Drop in butter and flour. Stir it up until the color changes slightly.
Finish up the sauce:
Pour in milk, broth, and garlic powder. Keep stirring until it's thickened up.
Make it creamy:
Mix in cream cheese until velvet-smooth.
Get your beans in:
Dunk the green beans in, let everything get heated. Taste and add more salt or pepper if you need.
Time to layer:
Mix in a handful of crispy onions. Spread it all in a baking dish, then cover everything with more onions.
Bake away:
Put it in the oven for about 20–25 minutes till it bubbles and the top is golden.

How to Choose the Best Green Beans

Fresh green beans are super tasty but mean some extra work—you'll need to rinse, trim, and cook them first. Using frozen makes things a breeze since they're good to go. Canned beans? Skip those—they end up mushy. Pick whatever fits the time you have and the taste you want.

Sauce Made Easy

The creamy sauce makes this dish pop. Sauté mushrooms and garlic in some butter first. Add flour so it gets thick, then stir in milk and broth until it's silky. Add cream cheese to level up the richness. Trust me, this beats store-bought sauce every time.

That Crunchy Finish

Don't skip the crispy onions—they're what make this dish legendary. Want to mix it up? Use crushed chips, bread crumbs, or toss on some cheese before baking. The crispy top keeps everyone reaching for seconds.

Prep Ahead—Zero Stress

You can get most of this dish ready a day early to make things easy. Just hold off on adding the crispy onions. Chill everything in the fridge. When it's go time, top with onions and bake. If it's cold from the fridge, give it a few extra minutes in the oven. Makes holiday cooking way less hectic.

Frequently Asked Questions

→ Can I swap frozen beans for fresh ones?

Absolutely! Fresh beans work great. Boil them for 5 minutes first and they'll have a nice crunch. Don’t forget to trim the ends off before cooking.

→ What's the best way to store leftovers?

Pop the leftovers in a sealed container and refrigerate. They'll be good for up to 3 days. Warm it up in the oven to keep the crispy top, or microwave it if you're in a rush (though the top won't be as crunchy).

→ Can I prepare this ahead of time?

For sure! Mix everything one day early, but wait to bake it. Wrap it up and store in the fridge. Throw on the crispy onions just before baking to keep them perfect.

→ How can I make this without any dairy?

No problem! Swap regular milk for oat or soy milk, and use oil or dairy-free butter instead of regular butter. Lots of stores carry non-dairy cream now too. Just double-check your crispy onions are dairy-free.

→ How can I make this with less salt?

It’s simple! Use low-sodium soup and adjust salt to your taste as you go. Taste test while cooking and add herbs like thyme or black pepper for extra flavor. Mushrooms naturally pack a punch of savory goodness!

Conclusion

Fan of this one? Try the creamy spinach too—it's just as good! If you're into deep flavors, the mushroom rice pairs amazingly with any meat dish.

09 1 cup milk (whole)
10 1/8 teaspoon powdered garlic
11 4 ounces cream cheese

Instructions

Step 01

Turn the oven on to 350º. Chop up mushrooms and mince the garlic.

Melt the butter in the pan and throw in the flour. Keep stirring until it forms a thick paste and turns lightly golden (takes about 2 minutes).

Step 04

Add the stock, milk, and garlic powder to the pan. Stir thoroughly, scraping up any cooked bits stuck to the pan. Cook until the liquid thickens slightly and starts bubbling.

Step 05

Drop cream cheese into the thickened sauce. Stir constantly till it's completely smooth and melted.

Step 06

Toss the frozen green beans into the pan. Mix them through the sauce and cook until they're heated and everything is bubbling gently. Taste and adjust the salt and pepper if you need to.

Step 07

Fold a quarter of the crispy onions into the mixture. Empty everything into a baking dish, then sprinkle the rest of the onions over the top.
