Ingredients for Herbed Dilly Zucchini Casserole
Now let’s gather our cast of characters – simple ingredients that work absolute magic together! I’m particular about a few things here (learned from years of making this casserole):

- 1 cup biscuit/baking mix – I use the good ol’ Bisquick, packed nice and level
- ½ cup grated Parmesan cheese – The real stuff, none of that powdery nonsense
- 1 tablespoon dill weed – Fresh is glorious, but dried works just fine too
- 1 teaspoon salt – Just regular table salt does the trick
- ⅛ teaspoon pepper – A little kick never hurt nobody
- 4 large eggs – Room temperature, lightly beaten until just combined
- ½ cup canola oil – Makes everything moist without overpowering
- 3 cups chopped zucchini – About 2 medium zucchinis, skin on for color
- 1 large onion – Chopped fine so it melts right into the bake
See? Nothing fancy – just good, honest ingredients that come together to make something extraordinary. Now let’s get mixing!
Equipment You’ll Need
Don’t worry – you won’t need any fancy gadgets for this one! Just grab:
- A trusty large mixing bowl
- 1½-quart baking dish (I use my old Pyrex)
- Measuring cups and spoons
- A good wooden spoon
That’s it – simple as pie (or should I say, simple as casserole)!
How to Make Herbed Dilly Zucchini Casserole
Alright darlin’, let’s get this show on the road! Making this casserole is easier than piecing together a jigsaw puzzle with only five pieces. Just follow these simple steps and you’ll have golden, herby perfection in no time.

Step 1: Mix Dry Ingredients
First things first – preheat that oven to 375°F (190°C) so it’s nice and toasty when we’re ready. Now grab your biggest mixing bowl – I use the same yellow Pyrex one I’ve had since ’76.
Dump in that biscuit mix, Parmesan cheese, dill weed, salt, and pepper. Stir ’em together real good with your wooden spoon until everything’s evenly distributed. You’ll know it’s ready when you see those little green flecks of dill dancing throughout the mixture like confetti!
Step 2: Add Wet Ingredients
Now for the fun part! Make a little well in the center of your dry ingredients and pour in those lightly beaten eggs and canola oil. Give it a good whisk until it comes together in a thick, smooth batter.
Don’t worry if it looks a bit lumpy at first – keep stirring and it’ll smooth right out. Then fold in your chopped zucchini and onion gently but thoroughly. The batter should be thick but pourable – if it seems too stiff, you can add a tablespoon of water to loosen it up.
Step 3: Bake to Perfection
Grease your baking dish with a bit of butter or cooking spray – I always use my fingers to get into the corners real good. Pour that beautiful green-speckled batter in and smooth the top with the back of your spoon. Pop it in the oven and bake uncovered for 25-30 minutes.
You’ll know it’s done when the edges pull away slightly from the sides and the top turns a gorgeous golden brown with little crispy bits around the edges. Oh, and that smell? Pure heaven!
Let it cool for about 5 minutes before serving – trust me, it’s worth the wait. The flavors settle in and the texture firms up just right. Now dig in and enjoy the fruits (or should I say, veggies?) of your labor!

Tips for the Best Herbed Dilly Zucchini Casserole
Here’s my tried-and-true secrets for casserole perfection:
- Fresh is fabulous: If you’ve got fresh dill, use it! Triple the amount (1 tbsp dried = 3 tbsp fresh) for extra zing.
- Drain those zucchinis: If your squash seems watery, let it sit in a colander for 10 minutes – nobody likes a soggy bottom!
- Golden rule: That perfect golden crust means it’s done – if it browns too fast, tent with foil.
- Rest time matters: Let it sit 5 minutes after baking – it’ll slice cleaner and taste even better.
Follow these little tricks and you’ll have folks begging for seconds!
Ingredient Substitutions and Variations
Now don’t you worry if you’re missing something – this casserole is as flexible as my old rolling pin! Here’s how you can mix things up:
- Gluten-free? Swap the biscuit mix for your favorite gluten-free blend – works like a charm!
- Herb options: No dill? Try fresh chives or parsley for a different but equally delicious twist.
- Cheese lovers: Toss in a handful of shredded cheddar or mozzarella for extra gooey goodness.
- Oil swap: Melted butter works instead of canola oil if you’re feeling fancy.
The beauty of this recipe? It welcomes all your creative tweaks with open arms!
Serving Suggestions for Herbed Dilly Zucchini Casserole
Oh sweetie, this casserole plays well with others! I love serving it alongside my crispy-skinned roasted chicken – the flavors dance together beautifully. For lighter meals, pair it with a simple tomato-cucumber salad. And don’t even get me started on how perfect it is with Sunday brunch eggs! Honestly though? Sometimes I just eat it straight from the pan with a big spoon – no shame in my game!
Storage and Reheating Instructions
Now don’t you fret about leftovers – this casserole keeps like a dream! Just cover it tight with foil or pop it in an airtight container in the fridge for up to 4 days. When you’re ready for round two, reheat individual portions in the microwave for about a minute, or warm the whole dish in a 350°F oven for 15-20 minutes until toasty again. Pro tip: A quick spritz of water before reheating keeps it moist as the day you baked it!
Nutritional Information
Now let’s talk numbers – but remember, these are just estimates since ingredients can vary. My trusty old cookbook says each serving (about a generous scoop) packs:

- 8g protein – Thanks to those eggs and Parmesan
- 15g carbs – With 2g fiber from all that zucchini goodness
Not too shabby for something that tastes this indulgent, if I do say so myself!
Frequently Asked Questions
Bless your heart for asking – here’s what folks wonder most about my Herbed Dilly Zucchini Casserole:
Can I freeze this casserole?
Absolutely! Wrap cooled portions tight in foil or freezer bags for up to 3 months. Thaw overnight in the fridge before reheating – though I’ll warn you, the texture’s best fresh!
Can I use dried dill instead of fresh?
Honey, I’ve done both for decades! Use 1 tablespoon dried dill weed (that’s the leafy part) – the flavor concentrates differently but still shines through beautifully.
My zucchini seems watery – what should I do?
Smart thinking! Grate it first, then let it sit in a colander for 10-15 minutes. Give it a gentle squeeze if needed – your casserole will thank you with perfect texture.
Can I make this ahead?
You bet! Mix everything except the zucchini and onion up to a day early. Fold in the veggies right before baking so they stay crisp-tender.
What if I don’t have biscuit mix?
No worries, sugar! Substitute with 1 cup flour + 1½ tsp baking powder + ¼ tsp salt. Works nearly as well in a pinch!
